Okay, so it doesn't have anything to do with Wiggler. It was really a typo. Milk and desserts are not uncommon.
Still can't find the answer. But we cannot delay any longer because we would need hints for other riddles. Half of the week is just about to be over.
It's probably Milk + Cake, since cake refers to desserts, but where would we find the answer page to that riddle, and lead us to the next one? I searched and searched, but still no luck.
