Flyboy of Underwhere (Underwhere, 3)

Sometimes even sidekicks have to step up.

Zeke's busy being the so-called Prince of Underwhere. His prissy sister, Stephanie, is some sort of pirate queen. But Hector? He's just a sidekick. Well, those days are over. Now only Hector can save the day—if he can survive swarms of sharp-beaked midget dinos, smart-aleck flying horses, angry armies in their undies, a really, really bad hypnotist, and a duel with deadly toilet plungers. . . all the ordinary wedgie weirdness of the tighty-whitie world under our own.
