No wonder their species name is SILLY-atilus! My crested is a little jumpy when I handle him, so I try to keep it to a minimum. Well, sometimes when I go to put him back in his cage, he'll take a flying leap and *smack* into the side of the rubbermaid! It looks bad but he shakes it off and then licks his lips afterwards as to say "I meant to do that!" Its really funny when he jumps and sticks to the side then slides down slowly, lol.
