Leon has a crush. A let-her-cut-in-line-at-the-water-fountain kind of crush. And he's got the perfect valentine. But this valentine has no intention of getting caught up in any romantic conspiracy. Love is yucky, kid! Valentine's Day is all about CANDY! the card yells at Leon, before leaping out the window and running away, leaving Leon to chase it across town, collecting kids along the way. Saying I love you has never been so yucky or so sweet.
