Hello everyone,
This may have been posted elsewhere already, but I just stumbled across it tonight. The site contains video and accompanying screenshots/gifs of various inflation scenes from Earthworm Jim, my favourite being from 'Day of the Fish':

Enjoy! ;)
My favourite is from the episode "The Wizard of Ooze", In which they inflate the Slug Queen with a vacuum. Her hysterical "creepy" screams add to it
