Birthday woes

So I made my students some chocolate frogs for their birthdays. It took me hours.... I have a student who has a birthday over Christmas break so I went to get him a chocolate frog.... AND THEY WERE GONE!?!?!?!?!?! I'm soo pissed! My frog molds are missing as well as the extra chocolate. Good thing I think I know what student is responsible. That's what I get for trying to be a nice teacher. LAME.
