Sometimes a mouse just has to bust out and do something big. That's why Marvin (also known as Merciless Marvin the Magnificent) decides it's time to lead Raymond the Rat and Fats the Fuse out of their cozy lair at the back of the mouse theatre and on to greater glory. Enough of stale popcorn and left over candy! It's time to go in search of...cheese! But the outside world can be a dangerous place. Is it possible Marvin has bitten off more cheddar than he can chew? Kids and parents alike will relish the laugh-out-loud humor of this hilarious crime caper, as narrated by the most delightful tough guy mouse in children's literature.
