- "Big gooberfish! Huge-o teeth!"
- ―Jar Jar Binks
Opee sea killers, also known to Gungans as Gooberfish, were creatures found in the oceans of Naboo. They contained evolutionary traits from multiple other animals, and had strong armor and jaws used in capturing their prey. In Star Wars Episode I an Opee sea killer is seen chasing an underwater vessel containing Obi-wan Kenobi, Qui-Gon Jinn, and Jar Jar Binks. While chasing the vessel the monster is eaten by a Sando aqua monster allowing the submarine to escape.
