Experiment 340 was the 340th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to cause massive depression by stealing cakes, pies and other sweets. 340 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.
Experiment 340 was mentioned in "Amnesio" when Hämsterviel stated, "After you sent me a sock hider, now you sent to me a pudding stealer?", hinting that he was caught by Gantu. However, Nodessertro did not appear in "Snafu". It is possible that they either set him free because he was considered useless, or he managed to escape.
The first 624 experiments, including Nodessertro, 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 Nodessertro 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.
Nodessertro is a small green mole-like experiment with a long rat-like tail, small beady eyes and three blue markings on his forehead, which match the blue markings on his stomach and back.
- Nodessertro's pod color is green.
