For this achievement, you will need to collect all the pellets in one combo. You will need a well levelled character.
You'll want to start with the manual pellets in front of you from the start, and then grind over the halfpipe. Make sure to manual out of the grind, collecting the ground pellet, and shooting yourself up the quarter pipe high enough to connect with the grind. Continue the grind to the lower level, and jump off to the left side aiming for the manual pellet (2nd room now). You will need a lot of speed here, but if done correctly, hold the manual up the quarter pipe, jumping to connecting with the grind on the higher pipes. Now grind around the corners, jumping off at the red pellet and finishing with the final 4 manual pellets.
