The B-Sides are unlocked after finding the cassette in the A-Side, or normal version, of their given level. So, for the B-Side of Chapter 5, starting from Section 2 you'll cross through the first two room to come to a large room with a squid statue in the center. Go down through the floor and enter the bubble and ride it right. Enter the next zone and jump across the platforms to the upper right corner to activate a switch. Drop down and go through the door to come to a room with two moving blocks. Dash up and land on the first block and ride it back to the right, jumping over the brambles along the way. Dash up to land on the block overhead and ride it back to the right, again jumping over the brambles. Activate the switch overhead and exit right through the now open door and cross the room you enter to exit on the right again to find the cassette room. After collecting the cassette and finishing the level, you'll get your rundown of strawberries collected and total deaths, plus the unlock for the B-Side.
B-Sides are more difficult version of the given chapter, with the same theme and mechanics of the level, just turned up to 11. The sections are roughly the same length as their A-Side counterparts as well. Every B-Side ends with an alternating pink and blue platforming section with their Crystal Heart at the very end. Plus, they have a bangin' alternate version of the level's theme song. That should be everything, so let's get into it. I'll break each section down into their own parts so they're easily identifiable.
Section One- Cross the screen to exit right to the first real zone.
- Jump into the bubble and ride it right, dashing up to activate the switch. Fall into the bubble below and ride it up, dashing right into the third bubble as you pass by. Ride that one up-right and exit right.
- Jump into the first bubble and ride it right, then dash down into the second bubble and ride it right. Dash up into the third bubble and ride it right. Dash up-right over the wall and fall into the fourth bubble, then ride it up-right and dash down-right after clearing the wall to fall into the fifth bubble. Ride it right and dash up into the sixth bubble, then ride it right and dash down-right at the end and exit right.
- Jump onto the first moving block and dash down to cause it to move, then jump off of it at its peak to clear the wall and grab onto the right side of the moving block below. Dash into it and jump off as it hits the end of its track to be launched across the room to another moving block. Ride it to the top and jump off to the end and climb through the ceiling to enter the next section.
Section Two- Head right first to enter a new zone.
- Jump out and dash right to grab onto the dropping moving platform and slide down to the bottom to drop off and grab the moving platform below as it comes across your path. Jump off of it as it reaches the end of its track to be launched into a green gem, where you'll dash up-right to grab onto another moving platform. Quickly jump over it and grab onto the right side, then jump to the next green gem and repeat the jumping over it and grabbing the other side. This time, jump off before you hit the ceiling and aim for the upper wall to climb through the ceiling.
- Dash into the bubble and ride it left, dashing up for the green gem. Bounce off the moving platform and grab onto the left side of the middle platform, then dash into it and jump off as it reaches the end of its track to be flung left to a small platform just before the end of the room. Exit left.
- Grab the key and take the bubble down to the starting room, where you'll use it on the locked gate and exit left.
- Jump into the first bubble and ride it left, dashing up for the second bubble, then alternate those steps for the third and fourth bubbles. In the fourth bubble, you'll dash down-left to reach the fifth bubble and ride it up-left directly into the sixth bubble, which you'll ride down-left directly into the seventh bubble. Ride this one left and dash up-left into the last bubble, which you'll ride right all the way through three zones.
- Jump onto the first moving block and dash down, jumping as the block hits the end of its tracks to be flung across the screen to grab onto another moving block. Jump off this one as it reaches its peak, then dash right in the tracks of the next moving block to cause it to smash into you. Grab onto it and quickly jump off to be flung to the last moving block. Jump off it as it reaches its peak and hold right to reach the wall to climb through the ceiling.
- Jump into the first orb as the second saw ahead is at the bottom of its path and ride it left, grabbing onto the wall and jumping into the second bubble, which you'll ride up until it breaks on the ceiling. Fall down and dash left through the gap to fall into the third bubble, which you'll ride right and dash up to grab onto the wall overhead just after the spikes. Climb up and jump into the fourth bubble, riding it left past the two saws, then dash up and fall into the fifth bubble. Ride it up and dash left through the small gap into the sixth bubble, which you'll ride up again and dash left through the two saws to fall to the ground below. Activate the switch in the floor and exit left through this zone and the next one.
- Stand on the lowest ledge and look down to see some blue gems and moving blocks. Dash down into the platform to make the blocks move, then jump and dash to grab the highest blue gem and grab onto the right side of the left wall. Jump over the top and get the left-most blue gem, then jump back over and get the green gem as you fall to grab the bottom blue gem and dash upward to grab onto the right side of the large block. Jump to the right block and jump over it to the other side, then jump to the last blue gem and fall down to the new opening below. Exit right.
- Grab the key and use it to unlock the gate floating in the middle of the room, then exit left.
- Jump into the bubble on the left and ride it right through two zones into another bubble, which you'll ride up into another zone.
- Jump off the platform and dash up-left to get the block to come towards you. Land on the jump pad to clear the brambles ahead and grab onto the left side of the moving block. Clear the brambles overhead and jump up to bounce off the jump pad and dash up-left to reach a switch. Activate it to cause the door nearby to open, then exit through the floor and fall to the bubble below, riding it up to pass the now open door and exit through the ceiling.
- Climb up and jump into the bubble as the saws are stopped and ride it right until it breaks on the wall, then fall into the bubble below and ride it up until it breaks on the ceiling, then grab onto the right wall and wait. As the first saw starts moving down, jump and dash through to land on the crumbling platform ahead, then repeat that through the next two gaps and end up in a bubble that you'll ride up. Dash out of it to grab onto the moving platform in the middle and ride it to the right, climbing or sliding to avoid the saws nearby. Get in the bubble and ride it up into another bubble, which you'll ride up-left until it breaks on the ceiling. Hold left to fall down and grab onto the wall to wait for the right time. As the saw hits the end of one of its paths, jump and dash to the bubble, which you'll ride up into the last bubble, which you'll dash up out of as it crosses the middle of the room. Activate the two switches to enter the next section.
Section Three- Jump off either side and grab onto the wall after you fall through two gaps. Jump to the lower wall, then jump to the center and dash up to activate the switch. Fall down to grab a green gem and dash to the right, falling down into another green gem. Grab onto the wall in the second narrow gap, then fall down and dash into the next switch and bounce off the wall to continue down. Grab the green gem and dash left and fall through the gaps until you can dash right to solid ground and exit right.
- You'll need to use the fish in this room to refill your dash to get all four blue gems and exit right.
- Jump and dash for the first platform, then jump and dash to fall between the first two walls. Dash into the green gem, then dash into the switch in the wall. Climb up and jump to the other side of the wall and fall all the way to the bottom to avoid the fish. Jump for the green gem and dash up to grab onto the right side of the wall and wait for the fish to come from beneath you, then fall on its head and bounce to refill your dash. Dash up to activate the switch, then grab onto the wall again and wait for the fish to return for more headaches. Bounce off its head again and dash up-right to reach the end and exit right.
- Jump into the first bubble and ride it up-right, then dash right to fall into the next bubble and ride it near the red walls ahead, then dash and grab onto the first one. Wait for the fish to fly nearby and creep jump slightly off the wall just before it would hit you to cause it to break the wall, then bounce off its head to refill your dash. Dash to the next wall and repeat that process twice to reach the end and exit right.
- As you jump across the crumbling platforms, you'll need to stun the fish to cause it to line up just right to finish the zone. Jump and dash to the first two platforms, then stun the fish as you transfer from the second to third platform. Jump and dash to the upper platform, then delay your jump and dash up to land on the lower platform to give the fish time to come back. Jump right and dash up-right as the fish passes by to be able to jump on its head and refill your dash to make it to the last crumbling platform, then jump and dash up-left and climb through the ceiling into the next section.
Section Four- Grab Leo and get to chuckin'. Exit right into the first real zone.
- Jump on the fish's head to stun it, then use the jump pad to boost up and throw Leo over the wall onto the next jump pad, then dash to join him and refill your dash. Grab him and fall onto the switch to activate it, then use the jump pad to boost and throw him over the next wall, then dash to join him. Wall bounce up the first two walls and jump to the center, throwing Leo on the way down. Dash to join him and exit right.
- Jump over the first fish and land on the switch to activate it, then walk through the door. Throw Leo over the second fish and bounce off its head, then dash into the switch in the ceiling to activate it. Fall down and grab Leo as you continue right. Jump over the third fish and throw Leo backwards to activate the switch, then grab him and jump over the fish again to go through the door. Stand on the center platform and jump on the fish's head, then throw Leo over the brambles to fall down onto the switch to open the door. Grab him and exit right.
- Throw Leo onto the moving block ahead to get the first blue gem, then jump onto the jump pad. Dash down into the jump pad, then dash right and grab Leo midair, aiming for the next jump pad. Cross the gap and throw Leo through the brambles to get the second blue gem, then dash to grab him midair and aim for the third jump pad. Bounce off the walls above and jump right. Throw Leo as you approach the wall, then grab the last blue gem and dash to the end of the zone. Exit right.
- Throw Leo through the first brambles, then jump and dash up-right into the green gem. Jump up and grab Leo in midair, then hold right until you would have bounced on the now fallen jump pad and throw Leo again. Dash to the last platform and jump up to grab Leo and throw him one last time, then dash to the end and exit right.
- Jump onto the blue block as it becomes usable, then jump and throw Leo onto the pink block with jump pads and dash to meet him there. Jump up to the blue block, then down to the pink one. Jump just before it goes dark and throw Leo in midair and dash so that the moving block ahead meets both of you as you fall. Ride it to the end and go through the door to find the crystal heart beating rhythmically. Dash into it and enjoy your achievement.
