Sushii Xhyvette stops by for a visit, but Harmony has other plans—like locking her adorable size 5 feet in the foot stocks ! With feathers, her dual-headed Hitachi, and those wicked fingernails, Harmony tests Sushii’s ticklish limits. But when the math questions start, things really go off the rails. Sushii can’t focus, can’t stop laughing, and definitely can’t get her multiplication right! “I think the tickling is melting your brain,” Harmony teases—and honestly, she might be right. This one’s as hilarious as it is cute!
