The Demon King sends Baby Beel some summer homework, containing a notebook which brings anything drawn in it to life. Next, Hilda brings Oga to Ishiyama High to collect prints of rare, powerful beasts, aka the delinquents, by whacking them with a giant fly swatter. During the chase, Baby Beel ends up planting several carnivorous Demon Plants, one of which grows into a massive giant causing havoc until Oga destroys it.
