Onion Transformation.

Has anyone seen my terrapin brother? He's smaller than you might think and not a great colour like he wouldn't exactly STAND OUT. If anyone has, please to enquire whether the large bag of onions he decided to put in the freezer - as a joke?? - has anything AT ALL to do with his complete psychological malfunction or whether he was indeed acting on behalf of the unknowable god of Onion Transformation.
