Exactly how steamy is this story?
PG
Whether it be the "Brotherhood Organized against Oppressive Boov" or the "Backyard telescope Observation Of Occupation by Boov!" Gratuity sure does run in to her fair share of BOOBs through the novel. It doesn't matter what state she's in—she seems to be able to track down a bunch of knuckleheads who think giggling at the word boob is amusing. Even she finds it ridiculous.
Boys cracking jokes about female body parts aside, the book doesn't have much in the way of steamy. We do get a lesson on how Boov babies are made, but since it doesn't involved the mom and dad even touching, we think we're safely in the PG range.
