Fire-bellies: 0.5 (with 10 being the worst). Mid-sized Cuban Tree Frogs: maybe 2...he was probably just hungry, but that frog was a genius at human manipulation.
One fire-belly tried to eat a twig because another toad had stepped on the other end, making it move. Then she spat it out, hopped down to the water and started pawing at her mouth like she was trying to wash the taste out.
