Then my laptop was stolen right from under my snout. Cheese niblets, how terrible! Could my friends and I find my computer and print my book all in time for the party?BONUS! After the story, read an extra Mini Mystery adventure: THE LAKE MONSTER. When a mysterious monster is sighted in a lake on Mouse Island, Geronimo is called in to investigate! But can he figure out this creature's secret?PLUS jokes galore!
