Nopony seriously believes in the sea-ponies. They're myth and legend, just stories and fairy tales to entertain foals.
Except Applejack. Applejack believes.

She believes she saw a sea-pony when she was a filly. She told everypony and they made fun of her. Over time even she began to wonder if it was just a foal's daydream.
Then one day Applebloom comes home wearing a strange necklace she found by the river, a small white scallop shell.

It convinces Applejack that sea-ponies are real and she sets out on a personal quest to find the sea-ponies.

More an adventure than a comedy, but when the CMC is involved, you know funny stuff will happen.

Scootaloo is the daughter of Lyra and Bonbon. Except she isn’t really. She’s adopted.

She and the other crusaders set out on a grand quest to seek out Scootaloo’s mother. Getting into all sorts of scrapes along the way.
