Chu Chu Space Station

The space mice called the Chu Chus (Not to be confused from the Zelda Series) have built their own space colony. They built the finest rockets for safe traveling, and safety precautions as well. However, it is vulnerable to the space cats known as Kapu Kapus. Now it's quite deserted. A few Chu Chus remain in this space station, since most Chu Chus escape away from the invasion of the Kapu Kapu.

There is other monsters in this space station. Good thing most of them don't eat Chu Chus:
Kapu Kapu (They're hungry for Chu Chus)
Kapu Kitten (They're baby versions of Kapu Kapu)
Mutant Chus (Bad Chu Chus)
Golden Mutant Chu (AVOID IT!!)
Shroob
Piranha Plants
Putrid Piranha
