I like the left ones.

the middle one

I wondered what happened to this guy!

hmm..the left ones definitely are more the usual style we know and enjoy so my Votes for those. The one of the right has sort of that Rugrats style look or a lost character that wasn't in the Jazz Jack Rabbit games. I think it really depends on how the character is portrayed in a personality and age sense.

the left character has that Shy or embarrased look, the middle has that deviant evil adult form, the one on the right has a little devil-like quality but in a younger character.

I like the ones on the left, the right looks a little too "buster bunny".

The middle one with the cloth diaper.

I like the one on the right

Middle

I like all three of them!! But if I have to pick just one, I choose the one on the left.

The left and middle were drawn on the same model.

the right one
