Hey! Apologies for the late reply, but if you’re talking about the purple glitch sprite, you will need to go up into a hole in the wall, and interact with the item on the ground.
If you’re taking about the tiles, remember, the white tiles are safe to stand on, and there are sometimes breaks in between a single flashing path, so you won’t need to go through it in one go
hope that helps
