What if you eat a desiccated frog?

I am currently am running Strahd for a group of beginner players, and have been trying to encourage imaginative and out of the box game play. One of them has just asked me (between session) what happens if they eat the frog-on-a-stick they found in the Death House. Like a good DM, I told them they will have to try it to find out but I'm not actually sure myself. I think it would be reasonable for it to be a negative effect and based on some research on eating frogs, paralysis might be a realistic response, but I am not sure. Anyone able to give advice/guidance?
