Mushroom, Panda and Robobunny will perform in the grand final of The Masked Singer tonight.
The three characters made it through to the last round after Destiny's Child singer Michelle Williams was revealed to be Rockhopper.
Earlier in the semi-final, Aled Jones was revealed as Traffic Cone.
But one character that has confused both the celebrity panel and viewers at home is Robobunny.
Ahead of the final, we take a look at some of Robobunny's most important clues and who fans think could be behind the mask.
Robobunny's songs
All the songs on The Masked Singer are clues to the character's identity.
So far, Robobunny has sung:
- Saving All My Love For You by Whitney Houston
- Shallow from A Star Is Born by Bradley Cooper and Lady Gaga
- Dynamite by BTS
- The Music of the Night from The Phantom of the Opera
- Somewhere Over The Rainbow by Judy Garland

Robobunny's biggest clues
In the first episode, Robobunny told viewers: "I might be made of metal but that doesn’t stop me making a splash."
A huge clue, which suggested Robobunny was from a famous family, was revealed in week four.
Robobunny said: "In my last performance, the panel were deeply moved by my version of “Shallow”, but they’ve still not even given one name that’s close. Ha-Ha-Ha! I LOVE IT!
"It’s well known that rabbits come from big families, and this bunny is no exception.
"You could definitely say it was Poppa Bunny that inspired my talent. And that’s the gospel truth. Do you want another truth?
"Sometimes people have said isn’t SHE good. Confused? Great!”
But his latest clue in week six saw some fans suggest Robobunny could be a member of Westlife, following the band's single More Than Words.
Robobunny said: "The panel still can't place the voice, and I'm not planned on getting busted anytime soon. HA-HA-HA! Everybody knows a bunny's got a "tail", but this bunny's got tales to tell, and I've got a very special way of doing that.
"Stories are personal things, and even though you might read plenty about me, being able to put things in my own words, and in my own voice, has always been very rewarding.
"You can do whatever you like with words, they can express emotions, take you to far-off places, and let you soar to great heights!
"Tonight, my performance will be filled with plenty of rocket fuel."
Who is Robobunny?
The Masked Singer viewers have had their say on Twitter.
Grover tweeted: "I'm guessing Mark Feehily from Westlife. Robobunny also mentioned a clue with the emphasis on words... which is about the only Westlife single I know."
Strictly's Oti Mabuse said: "Now I'm thinking Robobunny is Adam Lambert."
Steps' Claire Richards said: "#robobunny is @MarkusFeehily I don’t even want to hear anyone say it’s anyone else cos they’re wrong!!"
Jo Chirch said: "I think Robobunny is Russell Watson, Mark was one of my earlier guesses though."
