They, along with Rabbit, Tigger, Eeyore, and Gopher finally find him sitting near a log and is writing a card to someone called "Winifred".
He points out the reason while Christopher Robin is like this is because he's bitten by a smitten with love sickness, and this could mean he won't have time to play with Pooh and the others anymore.
He sets up a bait with Piglet dressed as a gentleman with a bouquet of flowers who quickly moves off the hill that he is standing on when he realizes that it is an anthill.
Pooh then notices a small firefly-like creature on his honey pot, which they assume that it is the smitten, which then flies off into the forest.
After Rabbit and Tigger describe unusual side effect that a smitten's bite can do in a song, they suddenly spot it and give chase.
Pooh finally catches it in a glass jar but finds himself lost and wonders around the woods until he tumbles down a cliff.
Believing that his best friend is gone forever, Pooh returns home only to find a Valentine's Day card from Christopher Robin.
Rabbit, Piglet, Gopher, Tigger, and Eeyore receive cards of their own while the smitten pays a visit to each of them.
