Kermit's Mixed-Up Valentines is a 2000 Muppet storybook featuring Kermit the Frog.

Kermit has received a number of Valentines from his friends, but they all neglected to attach a signature. Kermit studies the cards, which through a series of rebuses, hints about the sender, or blanks, reveal the giver. Miss Piggy's in particular is adorned with lipstick kisses, and says that she and Kermit go together like "green berry jelly" and peanut butter.
