Quest for the Popsicles

Do you think that a book called "Quest for the Popsicles" would be too...immature? That's the title of a book I'm hoping to write for my brother. It's about these two kids, Alex and River (I know, it's an odd name for a girl) who go on a quest for these magic popsicles on the fairy-inhabited Island of Somewhere (yes, that's its name). River has a pet parrot called Rainbow (who can recite the alphabet and other things) and there's a bunch of pirates trying to reach the popsicles first. I thought it up about a year ago.
