Tigerworm

A tigerworm was a type of sea slug found in Kara-Tur. They were carnivorous and had black and orange stripes like a tiger, hence their name.

By 1357 DR, tigerworms had infested E'Tyon Bay north of Singye in Koryo. They'd sunk four fishing boats and a merchant ship. Singye authorities offered a reward to any who could eliminate the menace.
