Sewer Can Is a Minor character in Apple & Onion who made a 0:02 second cameo in Pancake's Bus Tour. He is a member of what Onion calls "The Sewer People". He is most likely a reference to the movie IT because he lives in a sewer.
He is a creepy looking can who wears no clothes.
Hostile. (As seen in the 0:02 second scene were he pulls apple into the sewer while he was looking for his shoe.)
