Hi! So, me and one of my friends are in the middle of a prank war involving hiding things in each others food products. My current idea is to bake a batch of muffins, hide a toy in one of the muffins, and give that muffin to him. I'm not sure if you can cook a plastic spider or something into a muffin. Any ideas? Will this work? What should I put inside the muffin? Any better ideas for a prank? Thanks!
