The Wall of Water is a character who appears in the episode "Abstract". This creature acts as a barrier to Jermaine's new house in the Wasteland, and is instructed to only let in "the chosen". When James tells Jake that Jermaine lives beyond a wall of water, Jake initially thinks he means a waterfall.
He appears to be a giant wall of semi-solid water with a face on it.
Hey! None but the chosen may walk beyond the wall of water.
