Substitute Egg

In a trunk, Grizzy and the Lemmings find a large chocolate egg that contains a surprise. Everyone licks their chops with envy. In their argument and by accident, they send the coveted egg to a group of neighboring penguins. He is adopted by a pair of birds who begin to brood on him, as if they were his own offspring. Unimpressed, Grizzy and the Lemmings seek to seize it, but the entire bird colony intervenes.
