This has nothing to do with the cartoon Bluey.

Pinkie Pie is the silliest, goofiest pony in all of Ponyville. Maybe even Equestria. But everypony gets sad sometimes. But Pinkie Pie becomes so sad, her hair deflates. Then she starts turning gray, and when she’s even sadder than that, she starts turning blue.

After Pinkie Pie ends up annoying her friends, she no longer feels appreciated and wanted. So she runs somewhere far, far away. She arrives at Doom-and-Gloomsville, a town without any laughter or joy, where she meets Lavender Snow, a gloomy pony. (She is the pony form of my OC Yuki Aizaki.)

Through cheering up Lavender, will Pinkie realize how wonderful smiles and laughter can be again?
