The third epic English novel by Dav Pilkey!

A highly enjoyable picture novel  - brilliant for reluctant readers! The simple black-and-white illustrations on every page furnish comic-strip appeal. Includes several pages of flip-o-ramas that animate the action. 

The cranky lunch ladies quit after George and Harold fool them into baking super-volcanic krispy kupcakes that flood the school with gigantic green globs o' goo. Mr. Krupp finds replacements and fast, but he unwittingly hires the tentacled alien trio of Zorx, Klax, and Jennifer in disguise! Will they turn everyone in school into evil zombie nerds? Can George and Harold save the world before it's too late? All seems lost until the diabolical Zorx snaps his... um, tentacles in front of Mr. Krupp, and the power of wedgies comes to the rescue once again.
