Book #4 I'M TOO FOND OF MY FUR!
When my old friend Professor von Volt called to ask for help, I agreed immediately--even though it meant trekking halfway around the world to Mouse Everest! The trip was long and dangerous. I almost froze my tail off along the way. And then I was kidnapped by a yeti! Yes, it was truly an amazing adventure . . .

Book #5 FOUR MICE DEEP IN THE JUNGLE

They dragged me away on an airplane (I'm afraid of flying!) all the way to the jungle. There I was forced to eat bug soup, climb trees as tall as skyscrapers, swim in raging rivers, and even wrangle snakes. How would a 'fraidy mouse like me every survive?

Book #6 PAWS OFF, CHEDDARFACE!
