Any follow-up? I'm guessing he was fine and the phrase "This, too, shall pass" applies to styrofoam and tortoises ...

We once had a snapping turtle - a hatchling - whose only "command set" seemed to be

1. Bite it

2. If it tastes good, chew and swallow

3. If not, try again.

Repeat 1-3 ad infinitum.

He'd try to eat my thumb, even though it would be like me trying to take a bite from the middle of a wall - his head was 1/4 the size of my thumb ... but that didn't stop him from trying at every opportunity!
