Hehe. Thats so funny! Do you have a dog? might be learning off the dog. Yoda sometimes barks like a dog.
I don't know about chasing but Jibby has scratched his head with his tail before. Jibby has a love/hate relationship with his bell. He feeds it, humps it, kisses it, sleeps with it on his head. But he does attack it and when it comes back to hit him in the head he gets more and more angry at it. He doesn't realize he's actually making it hit him and its not alive!

Jibby also reeeally hates Yodas calcium perch. He does a very loud weird growl at it. And when I take it to clean, he follows and makes a ridiculas squark/growl (at the same time).

Hard to explain but its kind of funny!
