I can't find the actual project but the pattern for the Hungry Caterpillar Baby Cocoon and Hat by Angie Hartley is on Ravelry. It is SO cute!

Very Hungry Caterpillar - Adorable baby gift or costume! This doesn't link to a pattern but is easy to accomplish by changing up the colors on an existing pattern, then adding the simple details to the hat. Would work for knit or crochet.
