Absolem the Caterpillar

Absolem the Caterpillar (voice of Alan Rickman) is the all-knowing guardian of the Oraculum (a record of every Underland event past, present and future) in Disney's Tim Burton version of Alice in Wonderland. The Caterpillar is found in a mushroom forest and can be seen surrounded by a misty smoke. He challenges Alice to answer the loaded question, "Who are you?"
