Synopsis
Surreal, deranged Alice-in-Wonderland tale of bunny-suited brothers on phallic train to underwater brothel, with European comic art.
Two brothers wearing bunnysuits hop on a phallic train and travel to a mysterious underwater brothel. The story is very surreal and deranged in an Alice-in-Wonderland kind of way. The art style is quite original and seems influenced by European comics, in particular the likes of Jean Giraud.
