Icky No-No is a monster that loves to have fun. In one Muppet Time sketch, he sang a song about how he loves spaghetti and how it can be used for fun. Milton, on the other hand, would rather just eat spaghetti, which Icky No-No thinks is boring.

The puppet (often seen with droopy lavender eyelids) was later used on Mopatop's Shop as Mo Momo, Young Monster, Ginorman and others.
