A nice little Martian robot that has trouble keeping his hat on. He is nice except for the fact that he usually pushes you off a platform to your death.
Fire

Common traps that will burn heroes to death.
Garg

A speedy green monster with two eyes on stalks, commonly found creeping out of tunnels.
Pat Pat

Almost a kind of plant that opens and closes its "mouth" trying to chomp Keen if he comes too close. Similar to a Venus Fly Trap.
Tank Robot

These robots exist to kill any intruders. Even friendly ones.
Vorticon

A Vorticon Guard actually. Also appears as a Vorticon Commander.
Yorp

A harmless, happy alien.
