(Loosely based on "Winnie the Pooh and a Day for Eeyore")
On her way to work with her smoothie cart one morning, Sunny happens to bump into Sprout and notices that he's looking rather unhappy. Soon, she begins to feel like she's unintentionally forgotten all about him, and so has everypony else.
Determined to cheer Sprout up and make him happy again, Sunny convinces her friends to join with her to give Sprout a surprise birthday party. But they'll have to be quick, because Sprout's birthday is only a few days away!
Can Sunny and her friends get everything ready in time for Sprout's big day?
