These are two monsters that the player will encounter during the course of the level. I designed them with a good deal of function in mind. "The Locker" is not meant to be heavy on combat. In fact, the player will probably feel like they're at the bottom of the food chain more often than not. I also wanted to add a bit of puzzle elements to each creature.
For example; The creature at the top is found in darkened areas and will most likely be the players only source of light, however they will also be trying to eat the player. It will be up to them to figure out how to deal with such menaces in light of everything else.
