Alice is a young girl from England known for her famous adventures to Wonderland.
Background
At one point in Wonderland she met a hookah-smoking caterpillar sitting on a mushroom. Between puffs, the creature told Alice the mushroom was what she needed to change size--one side to make her taller, the other side to make her shorter. Since the girl had already been stretched and shrunk by a variety of cakes and potions, she had no trouble at all believing what the caterpillar said.
In another adventure underground, the caterpillar showed Alice a mushroom and said that if she ate the top of the mushroom, it would make her taller, and the stalk would make her shrink.[1][2]
In other adventures she met the Cheshire Cat.
