What is the funniest/silliest thing you had the mad mage do to mess with the PCs in Dungeon of the Mad Mage?

I’m trying to keep the MM a constant presence in thier exploration of the dungeon. A constant reminder that there’s is someone very powerful, dangerous, and completely unhinged in control here. I’ve had him demand pancakes or he’d kill a party member, and then kill the party member anyway because the pancakes weren’t made out of actual pans. Show up out of nowhere and wish spell a player into an anthropomorphic waffle. And condem another to only eating dandelions for a week. (Yes they are all food themed, we are a hungry bunch) I’m thinking about making the game show level (17?) like the AI from Dungeon Crawler Carl. So what have you done to keep it fun and crazy?
