4 🌟 Lots and Lots of fun. And lots and lots of undies. Some parents worry about “potty” humor when it comes to underwear books. That type of humor is absent in this work. Just the joy of finding a new pair of undies that fit after the others rip and fall off. The little monsters are adorable, the rhymes and cadence in line, and overall this is a fun a joyful read.
