The Prison Capsule, first seen in Lilo & Stitch, is a well-known object from Lilo & Stitch: The Series. This pill-shaped glass chamber is meant for containing the strongest of fugitives. Its rounded shape, slick surface, and extremely hard glass surface make it extremely difficult to break. Regardless, Stitch and several other experiments have been able to easily escape or break these capsules on multiple occasions.
- In "Topper", Jumba designed these prison capsules to be soundproof, as Stitch's screams could not be heard through the container when he was captured for his dysfunctional behavior.
- Ironically, this factor seems to be contradicted in "Snafu", as the captive Angel could be heard through her container when she sang her siren song backwards. It is possible that the container Jumba used for Stitch was designed especially for him, due to his extraordinary strength and power, while the one used for Angel (and all the other experiments) was just a regular container.
