For my daughter's 25th birthday. She has fallen in love with this game on her smart phone. All the birds are made of rice krispie treats covered with candy melts. Would not recommend this again because when you shape the RKT it compresses them and they get very hard and chewy. They were so hard we joked about, if the sling shot had been real (it was actually molded with candy clay) we could use it to sling the birds right off her balcony at the passing cars. But we didn't!
