Howcome - Experiment Series

Experiment Series

The first digit of the experiment numbers reflect what series of experiment they belong to. The official series of experiments, as stated by Jess Winfield, one of the executive producers, are as follows:

• 0-Series: Jumba's test batch, including many household helpers.
• 1-Series: Civic disturbances.
• 2-Series: Technological and scientific.
• 3-Series: Psychological.
• 4-Series: Mysterious series of mostly unknown experiments.
• 5-Series: Elemental manipulators.
• 6-Series: Battlefield or doomsday experiments with galactic implications.

For the most part, the colors of the experiment pods correspond to the series numbers, however some of the pods are colored incorrectly.

It is notable that though all experiments have unique capabilities and functions, most of them have some abilities in common. For one thing, most seem capable of scaling walls like a gecko (as Stitch frequently does); many are able to grow and retract an extra pair of arms and they all seem to be immune to aging, as the experiments remain the same while Lilo and the rest of humanity grow older in the episode "Skip", when Lilo uses the titular experiment to travel to the future to experience adulthood.
