The Rubber Ducky was revealed on premiere night as Anthony Anderson.

Jeong correctly guessed the celebrity after their performance of "Come on Eileen," pointing out that Anderson fit all of the clues given about the character, including one that other judges overlooked.

"This gentleman starred with Leo DiCaprio in the Oscar-winning 'The Departed,'" Jeong said of a photo of the actor shown during Rubber Ducky's intro video.

Fans were correct in thinking the Diver was Tom Sandoval.

The Diver said he's "been everyone's favorite person to hate," making panelists think he could've been "Maroon 5"  frontman Adam Levine, Scott Disick, or "Vanderpump Rules" star Tom Sandoval.

The latter, was a fan-favorite guess for weeks. On week two, after singing OneRepublic's "I Ain't Worried," Sandoval revealed he was beneath the mask.

So far, Jeong is two for two on his celebrity guesses.

"It was so much fun," Sandoval said of participating on the show. "Being able to come out here and perform, behind the mask, not being judged, just being judged on my performance, it was really nice."

Pickle was revealed as a wild card player.

On week two, Pickle joined the competition bringing "B.D.E.," big dill energy.

Pickle said their teachers thought they were a "bad boy with no future" who was only interested in sports and has rubbed elbows with Quentin Tarantino, Martin Scorsese, and Martin Short.

"I get paid a lot to talk," Pickle told the judges, saying that when he speaks, people listen.

Pickle's performance of "Pinball Wizard" by The Who left the panelists guessing a host of a talk show or podcast hosts like Craig Kilborn, Dax Shepard, Conan O'Brien, or Howard Stern.

The person behind the Cow is a Grammy winner.

The Cow performed "Bones" by Imagine Dragons on premiere night and "Treasure" by Bruno Mars on NFL night.

Cow says they didn't have a lot of positive male role models in their life, growing up in a household full of women. They're a parent of multiple children and are known for their "killer moves."

Over two weeks, panelists guessed Cow could be Shawn Stockman of Boyz II Men, Usher, and "Hamilton" star Leslie Odom Jr., Ne-Yo, Trey Songz, Nelly, and Jason Derulo.

Gazelle said they act and sing in movies.

After singing Alanis Morisette's "Uninvited," panelists guessed the Gazelle could be Camila Mendes, Lucy Hale, and Vanessa Hudgens.

The person revealed on September 10's pre-show that they have a connection to season four's Gremlin who was unmasked as Mickey Rourke.

During round two, Gazelle said they were pressured to change their name at 8 years old and said they could play the part of a villain.

Panelists refined their guesses to Leighton Meester, Constance Wu, and Auliʻi Cravalho after a performance of Katy Perry's "The One That Got Away."

The S'more said they're a household name who has made headlines.

S'more interacted with the crowd as they performed "Slow Hands" by Niall Horan on premiere night, leading panelists to believe the character may be a former boy band member.

Top guesses included New Kid on the Block's Joey McIntyre, Kevin Richardson of the Backstreet Boys because of the character's mustache, and "American Idol" runner-up, Justin Guarini.

During week two, S'more said they conquered the Broadway stage and accepted an opportunity to work with an industry legend in high school even though their father disapproved.

Jeong updated his guess to "Shang-Chi and the Legend of the Ten Rings" star Simu Liu.
