Clog, A.K.A. Experiment 143, is an illegal genetic experiment created by Jumba Jookiba. He is designed to clog up drains with his hair. His one true place is at the wig factory, clogging "pipes" that are actually air tubes that spits the hair through more pipes and into the main wig-making area, and Clog gets endless "sinks."
Clog is a orange hairball-like experiment with purple eyes and a red nose.
Clog can clog up drains such as bathtub, sink, swimming pool and others, with his hair.
Experiment 143 was the 143rd genetic experiment created by Jumba with Hämsterviel's funding. He was designed to clog up drains with his hair. 143 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.
The first 624 experiments, presumably including Clog, were rounded up by Leroy and taken to a stadium to be destroyed. However, Lilo, Stitch, Jumba, Pleakley, Reuben and Gantu arrived before the experiments could be destroyed.
It is unknown whether or not Clog participated in the following battle between the experiments and the Leroy clones.
The Leroys soon gained the upper hand in the battle, but were defeated when Lilo, Stitch, Reuben and several other experiments performed the song "Aloha `Oe", which caused the Leroy army to shut down due to the original Leroy's fail-safe.
- Clog's pod color is purple.
