Any Grunt Soldiers under Greegee's command?

Wouldn't Greegee have an army (or legion, which sounds cooler) that would be made up of several other things? I've included one of his, the Shai Gei, but maybe he would have more Greatures made to serve him, like a Groomba or Groopa. We can attempt to add more, unless we don't feel like doing it now.
