Electric blocks (Fat Cat)

 are hazards that serve a similar role to spikes seen in other Nitrome games. A warning to their danger appears when they are first introduced in level 6. The player must be careful not to let the Cat touch the blocks, or he will lose a life. Enemies often appear along the path between the electric blocks, making it more challenging for the player to protect the cat.

The blocks make their last appearance in level 19, where the player must guide the cat through a thin path with electric blocks on either sides. This level is mostly based upon mouse avoidance games.
