Pluto was a planet located in the Solar System.
There was a maximum security penitentiary on the planet. The penitentiary received and forwarded a Turtle Express package addressed to Faye Valentine sometime in the early-mid 21st century.[1]
In 2071, Udai Taxim, Tucan, and several inmates were assigned to the prison and loaded into a prison transport ship. The ship had a malfunction and the prisoners took control of it after it passed Ganymede. It was destroyed and did not make it to its destination.[2]
