Experiment 052 was the 52nd genetic experiment created by Jumba with Hämsterviel's funding. He was designed to turn things into chocolate. 052 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.
Stitch chased Coco throughout the house on Lilo's birthday wrecking everything. At first, Lilo was angry with Stitch for ruining her birthday, but Stitch showed her 052's power of turning objects into chocolate. Lilo changes her mind and declares it to be her best birthday ever instead while she, Stitch, and everyone else enjoys eating the chocolate-converted household objects. 052 was then named Coco.
The first 624 experiments, including Coco, 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 Coco 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 ʻOe", which caused the Leroy army to shut down due to the original Leroy's fail-safe.
Coco is a chocolate-colored pink-haired lizard/Stitch-like experiment with two buckteeth and a pink nose.
Coco can turn things into chocolate by touching them, though the object will remain the same color.
Coco has displayed the ability to speak fluent English, though he doesn't say much when he does.
- Coco appeared in the Disney Adventures Comics, where he was activated and given to Lilo.
- Coco's pod color is white.
