Betonwiser is not even a contestant, or a character. He is (was) a youtube accound that was replaced with Kerry Wiser.
For a while, he helped Clumsydog01 until he became I am Sesame Street of elmo fan of 2013 and spammed the comments and replaced many pages with just the text "Elmo fan here". He is now I am BFDIA of Dora Fan 2014 and his bio says "I like liking dora", and he gave away where he actually lives.
He was the creator of "Food Fight" a very unknown and poorly done object show.
