Loretta asks Eliot to keep her bunny rabbit for the weekend. So that he will not catch cold, Eliot puts the furry little creature under one of his father's hyper-proton lamps. Eliot quickly realises that the lamp has transformed the rabbit into a giant monster that eats everything in sight. With help from Kaytoo and Mimi, Eliot must find a way to get the rabbit back to normal size before Loretta returns for him.
