The larger ones are males, the smaller ones females. They will wander around, and reproduce if a male touches a female. They tend to die out rather quickly...
Yerp. I remixed with everybody's favorite characters... ...Zora and the Doctor! Yes, it makes no sense, but hey, it's a project. Anything can and will happen. I also made it so they didn't die as fast. You can thank me later when there are tons of tiny Zoras and Doctors wandering around reproducing themselves. In advance, you're welcome.
