Donatello's Portable Portal Generator goes on the fritz and accidentally brings escaped prisoners from Dimension X to Earth.
Tropes
- Deadly Environment Prison: Dimension X Penitentiary is set on an inhospitable planet inhabited by alien monsters.
- Plot Hole: To send the convicts back to Dimension X, the Turtles lead them to the exact location where they crossed over, yet the Turtles weren't there when it happened so they'd have no way of knowing where the criminals first appeared.
- Wizards from Outer Space: Skaarg wears a Mystical High Collar and wields a Magic Staff.
