The six singers will get narrowed down to three based on the judges and studio audience’s voting over the coming weeks. The three remaining disguised celebs will move on to the Super 9 alongside Banana, Frog, Kangaroo, Kitty, Turtle and White Tiger.

Taco narrowly missed advancing last week when he was unmasked and revealed to be Dancing with the Stars host Tom Bergeron. He joins Dionne Warwick (Mouse), Tony Hawk (Elephant), Chaka Khan (Miss Monster), Drew Carey (Llama) and Lil Wayne (Robot) in season 3’s pool of eliminated contestants.
