U-Port, A.K.A. Experiment 290, is an illegal genetic experiment created by Jumba Jookiba. He is designed to lie about delays. For example, if there are no delays, he will say there are delays. Conversely, if there are delays, he will say that there are no delays.
Experiment 290 was the 290th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to lie about delays.
290 and the other first 624 experiments were deactivated and smuggled to Earth by Jumba during his mission to capture Experiment 626.
All of the experiment pods were released and scattered across the island of Kauai.
At an unknown point, 290 was activated, captured, tamed, and named U-Port.
U-Port is a red Swirly (383)-like experiment with a small body, a disproportionately large head, ears, and eyes, and a single antenna in the middle of his head.
