Runaway Warehouse is the third world of Mario vs. Donkey Kong: Tipping Stars. As it is themed around machinery, Runaway Warehouse introduces the conveyor as a gameplay mechanic, with a special focus on Purple Conveyors, which can be collected and dragged across purple rivets. The world also introduces Thwomps and Mini Toads to the game, and also coincides with the debut of Cannon Kongs.
The world is set inside an automated storage building, where conveyor belts can be seen transporting crates through large-scale processing units. In levels with a higher ground, cranes can occasionally be seen picking up crates from tracks. At the bottom of the facility lies a footpath with measuring indicators and pipes. The two levels in Bonus mode that feature the Runaway Warehouse background are Level B-5 and Level B-6.
