In the song "Happy," from FNF SNS 2.5 Fanmade - Happy, Mickey exhibits peculiar behavior, displaying an unusual, slightly deranged happiness as he smiles and declares, "I discovered that happiness is a mask, worn by those who dwell in misery." As he begins to sing, BF joins in, and Mickey's mental state intensifies. In the final minute of the song, he erupts into a chilling laugh, "HOHOHOHO͜O̡O̧O̷͡͝O̴O͏̶͜O҉O͝O͟͏̢," revealing a descent into madness. His eyes widen, devoid of pupils, and he grits his teeth in a horrifying manner, his voice taking on a slightly altered tone. Despite this unsettling transformation, BF continues to sing, seemingly unfazed by the danger surrounding him, including the death threats and Mickey's increasingly maniacal state.
