Role in series
"Grandma's Kisses"
A sea leprechaun is the subject of a storybook that Grandma SquarePants often reads to SpongeBob. When SpongeBob tries to look grown up in front of his grandma, she reads the story to Patrick instead, calling it a "wonderful story about a magical sea leprechaun."
"Welcome to the Chum Bucket"
The same sea leprechaun reappears on the cover of the book. Plankton reads the story to SpongeBob, who falls asleep. Plankton mentions "the littlest sea elf."
"Pranks a Lot"
A dried-up sea leprechaun is one of Mr. Krabs' ghost self-defense items. He holds up a bottle with a small green hat, a miniature cane, and the dried-up remains of the sea leprechaun in it.
