Fed a Roly Poly Candy?

I found a little role poly in my room, so I put it in a small box with a damp tissue inside, and then I poked airholes in the lid. Without doing any research what so ever, I fed it a little bit of filling from a chocolate truffle. I didn't think that it would hurt him or anything, but this morning when I looked inside, he didn't look too well. I picked him up, and he was very weak and slow. Will he die? Is there anything I can do to save him?
