It's Little Miss Valentine's favorite time of year--Valentine's Day! But as she writes and delivers cards to her Mr. Men Little Miss friends, nothing goes as planned. Before long, she and her friends realize that all they need is their friendship and love for each other (though a little chocolate never hurts!).
- She is one of the few characters to represent an hoilday, the others are Mr. Christmas, Little Miss Christmas, Mr. Birthday and Little Miss Birthday.
- Unlike the rest of the hoilday-themed characters, She is the only hoilday-themed character that doesn't have a Mr. Men counterpart of herself.
- Her appearance is similar to Little Miss Sunshine's, except she is red and heart-shaped.
- She is the second heart-shaped character, with the first being Little Miss Hug.
