Marty Moose: Secret Sender Mystery finds Marty Moose off on his merry rounds as the postmouse of Little Ditch, when he discovers that no one will accept his letters! Animals all over town have been receiving very strange post from a mysterious sender, and if Marty wants to keep up a good job, he—with the "help" of his friend Nibbles—has got to solve the case.

Can he sniff out the sneaky secret sender, or will his whiskers lead him down the wrong burrow?
