Eeyore the lop-eared donkey-bunny
Yup, great name!
When I made the original costume for my daughter, I just went by the seat of my pants (no pattern). It was supposed to have upright bunny ears, but I couldn't make them work. Not much experience posting ears at that point, I guess.
KIP says THANK YOU! and is glad to know all that agony posing was worth it (I'll make it worth his time--I'm thinking bully stick!!)
Here's another version of Kip in his costume--doesn't he look all funny and...scrunched up?
