stripekazama bought me a drink in exchange for a doogle of his persona. Here he is in top-left being afraid of something (angel and devil narrowboats were added as the beer was consumed). Becoming the uber-swede, Stripe also added the Borking and Abba references (as well as filling the entire next page with a loving rendering of an Ikea superstore).
The SS FUCKTHISSHIT was added by  mishaela, and the submarine was poked in by FenRa.

Also the floating butt was that of the devil guy from Cow and Chicken. I think we established the whole cartoon was the result of satanic rituals. And rampant scissoring from the parents, who frankly didn't have the bits to try any other positions.
Actually, we decided they were the result of one of those all-legged creatures from Silent Hill being cut in half, which well matches the occult theme.
