Captain Underpants meets Star Wars in this hilariously funny series.

Cosmoe, Princess Dagger, Humphree and the gang are back for another wild space adventure. Humphree's all jazzed up at the chance to sell Galactic Hot Dogs at Crostini's Cosmic Carnival and Wonder Circus train. Cosmoe's not entirely convinced, but once his skills as a monster tamer are unveiled, the deal is done and the neon wiener officially joins the train.

Only things aren't quite what they seem at this circus, and pretty soon Cosmoe realizes he and his buddies are in more danger than ever. To get to the bottom of it all, they have to travel somewhere pretty familiar, giving readers a glimpse at last into Cosmoe's past and how he ended up aboard the Wiener in the first place.
