Character design for animated series

CME

We're making a kids animated series (8-12) and are looking for some help on character design. Think Rick and Morty for kids.

This contest is for the character design of Harry. Harry is a sentient, scientist, talking rabbit who takes our heroes on adventures throughout the galaxy (think doc brown from back to the future but in a Roger Rabbit sort of way). When on adventures, he has an inter-dimensional portal remote (kind of like AL from Quantum Leap). It would be good to include action oriented poses as well as relaxed. He is often a little frantic or neurotic. He has a space lab with HUD displays of graphs and charts and wavelengths and things. BG is not necessary, just trying to relay the vibe.

We have some renderings of the other characters. We think that Harry should match the tone in some way but still be super unique. Thx!
