Tent canopy
The tent canopy, more commonly known as just the canopy, is a tile introduced in Chip's Challenge 2. It obscures any tile that is hidden underneath it, unless Chip or Melinda have the secret eye equipped. It is first introduced in the level Flea Market.
Ants treat canopies as acting walls, and a blob will never move from a canopy tile to another canopy tile.
If a tile containing a canopy is in the radius of a time bomb when it explodes, the canopy will disappear, but everything under it will be protected.
