We have had two grass pokemon to date.
Also, about Emela, he is known as the elephant killer. So the way I see it, we have two options is we use him. One, there is an elephant that was long thought extinct that was once spotted in Africa, it having a very large skull that protrudes over its head. Emela can be a glass cannon rock, and the elephant can be a psychic type with physical wall and somewhat special sweeper status.
Wow, that sounded lame. That's okay, I have a better idea.
Impundulu- A vampire bird that can summon thunder with its wings.
Mamlambo- A creature with the body of a horse, the face of a fish, and the . . . wow, this is kind of an extreme animal. The best one I could find was a comical picture
This animal is known as a brain eater.
These two dark forces put against each other. Basically, you guys wanted a zombie, well here is a compromise to what is an actually good idea, and you also get a vampire bird.
