Cosmo

Cosmo is a scientist and Sprout is a zombie.

Cosmo is a scientist, short, with curly dark brown hair, tanned skin, and brown eyes. He wears an unbuttoned shirt with a black T-shirt underneath and a belt with various test tubes attached.

So, here's the plot.

Cosmo was 19 years old, and he'd been trying for a long time to create a living creature out of dead bits of flesh and the like. And finally, he succeeded. Cosmo nicknamed him Sprout. Sprout was slightly taller than Cosmo, though Cosmo treated him like a child.
