Trivia[]

  • He was originally created by Trevor Henderson, also known as SlimySwampGhost, who is well known for creating various internet cryptids, most notably Siren Head.
  • According to Henderson, Siren Head would be left unharmed by an E.M.P, as he is mostly organic.
  • He and Slenderman do not get along as shown in SMG4: SSENMODNAR - 3,826,412 SUB SPECIAL.
  • Despite his height being 40 feet tall, he is much shorter in SMG4.
  • He is the third infamously terrifying monster Mario has inexplicably befriended, after Slenderman and Weegee.
  • His rivalry with Slenderman is similar to Woody and Buzz Lightyear's relationship in Toy Story 1.
