Warpulator

Warpulator is a time travel device "recombobulated" from the downloaded flight data of the Shroob Mothership by Stuffwell. It has the power to reverse the flow of time, and can send individuals to a predestined point, along with any, and all of their current inventory and statistics. It tends to only be used near the ending of the game, where the Mario brothers end up trapped at a point of no return, and need to battle Princess Shroob so they can revert back, and do any tasks they might have missed. It can also be used post-Elder Princess Shroob defeat, but at the cost of the Castle being re-taken over by the Shroobs.
