Big Green Caterpillar

The Big Green Caterpillar (generically referred to by Prima as a "worm") is a giant harmless insect appearing only in Super Mario Galaxy. Specifically, it appears in the Gusty Garden Galaxy's mission called The Dirty Tricks of Major Burrows, where it is found after Mario uses a Ground Pound on a specific stump on a giant apple planet. Once Mario does this, the caterpillar bursts out of the apple before crawling into another apple planet. After doing this process two more times, the caterpillar instead leads to a Launch Star, which Mario can use to continue. The caterpillar is most likely based on the larva of the codling moth, due to its tendency to burrow into apples.
