Blue wall
A blue wall, closer to a teal-blue hue in the MS version despite its official name, is a tile that can take on one of two indistinguishable possibilities:
- Fake blue walls, which act as dirt: Chip will turn it into floor when he attempts to step through it, but while it exists, Chip cannot push blocks over them and monsters cannot pass them.
- Real blue walls, which turn gray when Chip pushes on them, identifying them as walls.

The only way to find out whether a blue wall is fake or real in Chip's Challenge 1 is to attempt to step through it. In Chip's Challenge 2, the player can check if a blue wall is real or fake without attempting to move into it by "slapping" it in the way one would slap a block. There is also an item, the secret eye, which distinguishes fake blue walls from real ones using the graphic of a fake blue wall from the in-game level editor. Of course, one can also simply view a map of the level or open it in an editor; most editors use a more grayish-blue color for real blue walls and a teal square with a white outline for fake ones.
In CC2, blue walls can also be revealed by ice blocks, directional blocks, player mirrors, bowling balls, and rovers.
