The Cave Garg is a big brown Garg that is found in Marooned on Mars - Galaxy mod, and is the only creature in the mod that does not originate from the original Keen 1, and instead a creature from another game.
The Cave Garg is only encountered in the Secret City, on Normal and Hard difficulties. It takes the place of a Garg that was in the top-right of the level in the original Keen 1. It walks around, takes a nap when it reaches its nest, wakes up, and it repeats the actions until Keen stuns it by shooting the Cave Garg 5 times.
The Cave Garg is a Little Ampton replacement.
