One of the first words revealed. It is made of wood, and approximately twice the hight of maxwell. In games released before Scribblenauts Unlimited, many variations of ladders were put into the game at different lenghts and heights. The original dilapidated ladder does not exist in Scribblenauts Unlimited, only Fixed Ladders and Rope Ladders can be found in-game.
Ladders are made of wood, so they can burn, are buoyant, and have wood properties.
Maxwell can climb ladders to reach places he normally cannot access.
