On safari in Australia, a wealthy traveler meets a talking wallaby who loves Japan and never thought he'd get a chance to visit. It turns out this traveler is also the principal of a private school in Japan, and before the little wallaby knows it, he's been whisked away to the land of the rising sun and plunked in front of a class full of students as a substitute teacher! Mr. Wallaby will need all the courage in his footlong frame to take responsibility for all these kids-and they may just find his cuteness too distracting to learn anything, too!
