Rhyl

The rhyl was a worm-like creature. Children from Ba'ku, such as Artim, keep them as pets. (Star Trek: Insurrection)

Background

It is unknown if this "palm pet" is native to the planet, or if the Ba'ku brought them from their homeworld. The script of Insurrection described the animal as "a colorful cross between a caterpillar and a jellyfish".

Its name comes from design notes, and was not mentioned in the movie.

A licensed tie-in beanie toy of the Ba'ku rhyl was made by The Idea Company and sold, for a short time, at Star Trek: The Experience at the Las Vegas Hilton.
