Tutorial on how to do the glitchy nugget / nugget wallclip trick.

Requirements:

1. Level with the in-ground checkpoints you crawl out of (NOT the teleporters)
2. An unclaimed upgrade can
3. Nugget

To do the wallclip in Supermarket specifically:

1. Get to the 3rd checkpoint (right after getting Nugget)
2. Dash in front of the can, pause before claiming the can, then respawn at checkpoint. (Doesn't need to be a dash, but that's easiest)
3. Nugget is now glitchy. The further away from the checkpoint you get, the glitchier he gets.
4. Get far enough away from the checkpoint so that Nugget's movement is fast enough to clip you through the wall.
5. Face away from the wall you want to clip through. (If you don't face away, you'll likely just wall-slide against the wall).
6. As Nugget starts moving up and towards the wall, double jump and grapple, and nugget should drag you through the wall.
