Unknown to most ponies, even to her closest friends, Fluttershy has a baby sister who was born with a mental disability. On the first day of school, Fluttershy wants to ensure her sister has the best possible experience, so she takes matters into her own hooves. But after overstepping her boundaries, Blossom snaps back at her sister claiming she doesn't need her help. Now no longer taking help from her sister Fluttershy, how will Blossom fair on her own?

(This is in no way making fun of any mental disability.)
