The adventure begins in the Atlantic Ocean when Freddi Fish visits Grandma Grouper with a gift of flowers.

The Wii version's availability was limited by legal problems concerning its development. In 2008, it was released on the Wii under the title Freddi Fish in Kelp Seed Mystery as well as Windows and Macintosh, and on Android with a shortened title Freddi Fish and the Missing Kelp Seeds.

Freddi Fish and the Case of the Missing Kelp Seeds is a 1994 video game and the first of five adventure games in the Freddi Fish series of games developed and published by Humongous Entertainment.
