There's no need to write a step-by-step guide for any of these levels because they are extremely easy and straightforward, but for those of you who want to collect all of the silver and gold canisters, here are their locations on this level (which Toa to use will be symbolized by color):
Gold #1: At the first Hero area go to the waterfall to your left and use WHITE to build an ice walkway to the canister.
Silver #1: At the second Hero area it's to your right just passed the black mask.
Silver #2: In the same area go to the left this time and climb the wall with BLACK to reach it.
Gold #2: At the far right end of this Hero area use VEZON* to build the black brick creature and smash your way to the canister.
Gold #3: After interacting with the gold bricks enter the hallway and immediately turn right. Use BLUE to rearrange the wall to open a room to this canister.
Silver #3: Before crossing the lava with RED look left and use BROWN on the wall to break it down.
Silver #4: While on the lava with RED turn left and it will be by the lava fall.
Gold #4: At the very beginning of the third Hero area turn to the left and use GREEN to break down the boulders to reach the final Gold Canister.
Silver #5: Just across from the last Gold Canister use GREEN to jump across the gap to the final Silver Canister.
*Vezon is unlocked as a playable character after completing the game.
Also, you will need to upgrade your characters at the store to get certain canisters. I suggest searching for canisters on your second playthrough of the game since you will need to unlock Vezon to get them all anyway.
