I had a juvie corn houdini himself out of a 10 gallon terrarium with a screen top that was weighted. Never could figure out how he did it. I thought him long gone...months later I took a 2 am moonlit pee as my cat had stunk up my bathroom something awful and I looked down in the gravel and who do I see? Mr bloodred pied sided corn motoring my way. Pure, blind, stupid luck I found him.
