A psychotic snake that ravages the homeless people on the streets of New York. He is rumoned to be over 28 feet long, and can travel at speeds of up to 161 feet per second. A "silithisis" feeds mainly on black people that are homeless, but if tempted, he will eat the Irish.
As Jerome was selling his 99 cent watches, a silithisis engulfed him in a swift bite.
