What's gloppy, purple, and comes in a jar? Daphne Trusk isn't quite sure -- but she calls it Blubb. Blubb is no ordinary purple blob, though. He's really Mr. Hero, Champion of Truth and justice. He can turn into anything he wants -- a cat, a duck, even a regular boy. Blubb was invented by genius Sidney Agenda, a student at a special school for aspiring heroes. Sidney has just been captured by evil Lowell Gravenstien and his band of kid ninjas. Now it's up to Daphne and Blubb to rescue Sidney.
But first they have to find him....
