Mine are the names that drag performers come up with. Some drag name puns I’ve come up with that don’t seem to be taken yet are Otto Ajob, Hugo Furst, Mel Functional, Anita Jobb, and Joan Acult.
The product descriptions for some of the Woobles have plenty of puns. My top two are the ones from Cornelius the Bee ("You might say he's quite the busy bee, and you won’t be able to help pollen in love with this honey of a guy") and Kaida the Dragon ("[...] she’s so char-ming that we don’t even mind her tendency to take the last piece of anything, wyvern you like it or not").
