Monk Brought a Scorpion to Work Today

I got a text from Monk yesterday evening that was kinda strange. He said he had caught a scorpion for Brody. Brody is my 5 year old.

Here's the text:

I never really thought of it again until Monk walks in the studio with a jar with a green lid with air holes punched in it. Monk said he found it in his basement. Yikes. Brody will think this is the coolest gift EVER.

Brody is out of town this week so I'm going to try to keep it alive til he gets back. What do scorpions eat?
