We think this turtle kigurumi onesie costume is the cutest reptile at Animal Costumes Shop. It's definitely in the top 10 anyways.
The turtle kigurumi comes with a super-cute turtle face on the costume's hood, so you can dress as a turtle without covering your own face. It also has a (soft) shell on its back, a drawstring hood and pockets.
These adult animal costumes are known as 'kigurumi pyjamas' in Japan where the craze originates; kigurumi meaning 'a soft toy that you wear'. We think this describes nicely how fun and comfy this turtle costume is.
