Stairs



Stairs were used by Humanoids and other bipedal species to allow them to climb to higher ground in a more easy manner.

They were especially needed in places where elevators were unavailable or not functioning, such as the Gotham Hotel or other buildings that had multiple levels.

When Marvin, Wendy and Wonder Dog sneaked into Doctor LeBon's headquarters, they made there way upstairs to spy on him and Wilbur.

When the two criminals started to head into their direction, they quickly ran down the stairs and into the galley of a flying saucer to hide from them.
