Reptile Rick was an act hired by Raven for Cory's birthday party.
After Raven promised Cory the best birthday ever, she wound up called an Australian party act named Reptile Rick. The kids became exited.
When Rick arrived, he ate the food that Victor and Tanya got sick from, causing him to be out of commission. Raven took his place, but was less than exiting. In the end, Rick returned and showed the kids his pet pig Luann giving birth.
