Brick monsters

Brick monsters are enemies in Plunger.

Appearance
Brick monsters look like a small, square-shaped creatures with a white face looking like a square skull and a pair of small, red stubs for legs. Two similiar stubs are also found on the Brick Monster's sides and might function as arms. A small propeller can also appear on the top of a Brick Monster.

Game information
In game, Brick Monsters will cling to walls and walk around either clockwise or counter-clockwise. If a Brick Monster touches a point where the wall turns, they will simply turn along and continue moving. If a Brick Monster touches one of Plunger's arms, they will start to walk on it towards Plunger and destroy him on contact. If Plunger changes the direction of his arms, the Brick Monster will pull out a small propeller and continue moving in its' direction until it lands on a wall. This will cause it to continue walking on the wall.
