When Regina arrives in Wonderland with Jefferson, they come across the Caterpillar smoking a hookah. He asks the two strangers "Who are you?", blowing smoke in their faces. The Caterpillar is in Henry's storybook.
After the realms are restored, following the Final Battle of Storybrooke, the Caterpillar continues smoking.
Once Upon a Time in Wonderland
It is revealed that the Caterpillar owns a place called Underland which is inside the giant mushroom he is commonly seen residing on. He is an enemy of Will Scarlet, who owes the Caterpillar a multitude of debts. When Jafar takes over the Red Queen's palace, he manages to get the Caterpillar to divulge information about a fearsome creature known as the Jabberwocky. Some time later down the track, Alice shrinks herself with some of the Magic Mushroom and manages to take the Lost-and-Found from the Caterpillar without him realizing.
