Greeb is a fellow in Millard's Mansion (The show he is in), and is probably the friendliest creature there. He is a very silly and joyful alien who welcomes everyone new to the mansion. He loves doing taxidermy and collecting insects. He's weird and creative and loves to have fun. He's friends with almost everyone in the mansion and likes to learn all their hobbies to make them happy.

His voice isn't a typical alien voice, but if you wanna add some spice onto it that's fine! Just don't make it too nasally or annoying lol. He doesn't sound too young but he has a unique voice.
