I say Dragon, Jeff says Dinosaur but Tyler says...I am never taking this off. Matter of fact, he put it on in the store yesterday at 2:00pm and begged to wear it as pj's and as far as I know is still wearing it but he hasn't woken up yet. Granddaddy told me on the phone last night, "Ahhh, let the poor boy sleep in his dragon costume"...let's hope he wasn't drunk! The hood is what worries me about sleeping in it but at least it's a snug fit. He even wears it in the car seat. He walks around the house and asks if you wanna ride his tail.
