Bio
Experiment 158 was the 158th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to sniff out any lost or missing person or item.

158 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 after this, Experiment 158 was activated and captured by Lilo and Stitch.

Lilo & Stitch: The Series
After Lilo and Stitch captured 158 and named him Finder, Lilo used Finder for show-and-tell at her school, where Finder quickly found all of the girls' lost belongings.

Finder was later assigned to find Hämsterviel. He tracked Hämsterviel to the Edmonds' home, but Lilo was convinced that Finder had made an error when Mertle] covered up for Hämsterviel.

The next day, Lilo and Finder arrived at the local dog pound to retrieve Stitch, who revealed that Finder had indeed tracked down Hämsterviel.

Lilo, Stitch and Finder returned to the Edmonds' house, to find that Gantu had fled with Mertle and Hämsterviel. Using his helicopter-like flying ability, Finder was able to track Gantu's ship down.

Finder was shortly after found a one true place operating the beach Lost and Found service.

Finder reappeared in "Drowsy".

In "Skip", Finder was one of the wanted fugitives in an alternate future where Hämsterviel ruled Earth.

In "Ploot", Finder was one of the second team of experiments (along with Babyfier and Drowsy  formed to try and stop Ploot. However, Ploot was easily able to defeat them.

In "Snafu", Finder was one of the experiments who joined Lilo and Stitch on a mission to rescue Gantu's captive experiments. Finder helped break into the ship and free the captive experiments.

Leroy & Stitch
The first 624 experiments, including Finder, were round 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 Finder 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 failsafe.
