It's Doris' birthday and Ben the monster has planned a surprise party. To prepare, he cleans the house, makes a cake and flosses his teeth (and horns!). At this unique monster bash, the birthday dragon blows on her candles to light them, the robot is a little too enthusiastic about hitting the birthday pinata, and the host monster finds horns an impediment in a game of trampoline. Each spread, illustrated in panels, contains its own discreet episode and joke, which makes it perfect for little children to enjoy.
