Waluigi Hat was a contestant in DATCM Beta.
Since he never submitted a challenge, nor did he do much in his RFTF entries, his personality is quite a mystery.
Waluigi Hat's only interaction with the camp was selecting Z's Jacket to be his teammate. Since Z's Jacket did not choose a teammate himself, they were automatically paired to create the Memeing Gophers. Shortly after the camp began, Waluigi Hat quit for reasons unexplained.
