Fans were introduced to six new singers -- The T-Rex, The Rhino, The Astronaut, The Bear, The Swan and The Night Angel -- and they all sang their hearts out for a chance to move on to next week's Group C playoffs.
This week, the panel of celebrity "detectives" -- including Robin Thicke, Nicole Scherzinger, Ken Jeong, and Jenny McCarthy -- tried their best to figure out the new singers' real identities after only one clue package and one performance.
After all six hidden hopefuls belted out some iconic tunes, the audience members in the theater, as well as the panelists, voted on who would be moving on and who would be getting the axe.
After all the votes were cast, America had to bid farewell to The Bear!
For her part, The Bear belted out an energetic and unexpected performance of Sir Mix-A-Lot's "Baby Got Back," but even that wasn't enough to earn her votes.
However, on The Masked Singer, whenever viewers have to bid farewell, they also get the reward of finding out if their wild guesses were on the money or if they totally missed the mark.
"I was the last person cast in Group B, and by that point, they only had two choices: obviously a taco costume, and the other was a jellyfish," Bergeron explained with a cringe. "So I think I picked the right one."
He explained that watching a Taco sing and dance is probably "more entertaining than watching something that you think might sting you."
The costume was one of the strangest and goofiest in the show's three seasons -- which is saying a lot. And for Bergeron, the crunchy shell and bulbous red tomato head with a cartoonish face presented some challenges.
"The tomato mask was the easiest part, the hardest part was the hard-shelled taco itself," he recalled. "The second number I did was 'Bossa Nova Baby,' an Elvis Presley tune -- you try shaking your hips in a taco shell. It ain't happenin'!"
