Muffin the Mule (2005) S01 E01 Wish Upon a Star

Despite stargazing one cool winter's night with Muffin the Mule and Monty the mischievous monkey making a five-pointed "star" out of "silver paper and cardboard" as well as Peregrine the penguin building a "highly powerful telescope" to study the stars and then seeing an alien that looks just like Willie the Worm, Louise the lamb learns that all real wishes must always be kept secret.
