Escape Pod

The Gem Warship Escape Pod is a Gem-activated pod fired from the middle finger of the Gem Warship in emergencies.

"Jail Break"
Peridot used a pod to escape the crashing ship and landed somewhere on Earth in North America.

"Joy Ride"
Steven and the cool kids discover the abandoned pod a few miles outside of Beach City. Under peer pressure, Steven enters the pod where he takes control of it. The pods begins to act like a manually-controlled Plug Robonoid in shape and movement. However, the pod locks down during his shenanigans and begins filling with a breathable liquid. Afterwards, the pod starts firing on the cool kids and shoots distress flares into the air before finally being cleaved in half by Garnet.
