I used to have problems with Homer and Sprocket both. Sprocket loved being out, and she would wrap around anything that was close because she just didnt like going back in the tank. Once inside tho, she just chilled out. Homer kept going up my arm or gettin himself on the side of the tank when i would try to put him back. He wasnt one for comming out, but once you had him out he was a good little boy.
