Yeah, the Caterpillar was always smoking from a 'hubbly-bubbly' pipe (like they have in Morocco, and stuff)...as 'Alice In Wonderland' is an account of Lewis Carrols 'trips', there are alot of drug references...the grow-big, and grow small mushrooms (fly algaric), and the LSD references too..lol
Lewis was a fucked up dude, man...
