You wouldn't think so but Suie was a very determined little snapper. She'd pretend to be asleep and then run full speed into walls when no one was looking. And once she toppled her entire 10gallon glass tank just 'cuz. That last one earned her the nickname. She gave up the tendency when her shell healed so that led me to believe it was pretty desperate and very intentional. Not to mention more than a little bit impressive.
