Bubble Gum Bison avoids bubble baths…until that becomes impossible.Bubble Gum Bison is having a great day, playing with her brother (whom readers may recall from 2022's Blue Bison Needs a Haircut), conducting science experiments at school, and chewing bubble gum and blowing bright-pink bubbles with her friends on the playground. Even slipping in a big mud puddle is fun until her mother insists that Bubble Gum Bison take a bath. No way! A muddy Bubble Gum Bison escapes out the bathroom window and heads to the playground, but all her friends have gone home. She accidentally falls into a giant pile of chewed-up bubble gum and then lands in a heap of feathers. Now she desperately wants a bath, but for some reason, the whole town is out of water. In anger, Bubble Gum Bison nearly rams her head into a rock, but she hears her brother Blue Bison ramming his head into a nearby metal pipe surrounded by a puddle of water. Could that pipe have something to do with the town's dwindling water supply? Working together, the siblings find a way to put things right. Digitally created illustrations dominated by bubble gum pink depict an adorably anthropomorphic animal cast with big eyes and rounded features; Bubble Gum Bison's mood shifts-from unfettered exuberance while rolling in the mud to pure irritation when she learns the water's all gone-are a delight.Readers will wish all bad days were as fun as the one depicted here.
