YAY! My dad got him out.
He got the ladder, stuck his hand under the hole with a carrot in his hand, and TJ slowly (but surely) came out after 10 minutes. It was hard though, because when he was in my dads hands he jumped but luckily my dad caught him in mid-air. Currently, he is sleeping soundly in his cage. It's good he made that hole, or we wouldn't have known where he was! He had fallen through a hole, and was on a new level; so he couldn't get back out. If he didn't chew that hole, he would have been stuck in there forever. x.x
Thanks for all the help guys.
