Journey to the center of that thing

"Explorers Troop 301 has explored a lot of planets hoping to find a place to call home. But their latest mission feels like the most boring ever--until they get chased by giant ANTibodies straight into the planet's open mouth! Can Finn and his friends make it through all thirty-five stomachs, battle an army of ants, out-whiz a super-computer in a deadly game of trivia, and find a way out? Or are they doomed to be part of the planet's balanced diet?"--Provided by publisher.
