Clad in a faux sheepskin jacket, cream pantaloon trousers and a pair of brown boots, Beagle showed off his moves on the dance floor on Sunday night.
Alongside Beagle was Squirrel, Carwash, Flamingo, Rubber Chicken and Frog, who all took to the stage with presenter Joel Dommett taking the reigns.
The remaining six characters battled it out on the dance floor as they hoped to win over the judges and viewers.
Flamingo was unmasked as Louise Redknapp last night, but now fans are looking into it further and have started piecing together clues for the rest of the characters.
So far, here's what is suspected of Beagle...
When Beagle first entered the competition, fans were given clues for who it could be.
Beagle is someone who loves a competition, is said to have kicked things off when he got his "first pair of boots", and he also alluded to flying planes.
So far, it's believed McFly's Harry Judd, former cricketer Freddie Flintoff, ex-footballer Jamie Redknapp and Celebrity MasterChef winner Greg Rutherford are all suspects for Beagle.
This comes after Viper became the first character to be unmasked on Saturday evening after losing out to Beetroot and Knickerbocker Glory in the bottom three.
Zip, Llama and Scarecrow made it safely to the next round, however, and fans were stunned as Diversity star Jordan Banjo was revealed to be behind the forked tongue.
After he was unmasked, Jordan joked: "This entire experience was worth it just to be called Anthony Joshua."
Opening up about his reason for taking part, Jordan said: "After the past year we all need to have some fun!"
Admitting that he had found it "super difficult" to keep it a secret, he also added about leaving the competition at this point: "Part of me was gutted but also relieved!"
This comes after the Masked Singer proved to be a huge ratings success for ITV, with Sausage's win in February this year breaking records.
The final of the second series peaked at 10.6million, with an average of 8.6million tuning in to watch the show - which was up by 2.2million on the last series in 2020.
Sausage managed to beat Badger and Robin to secure the crown and was unmasked as singer Joss Stone, leaving the judges utterly speechless.
Meanwhile, Badger was unmasked as singer-songwriter Ne-Yo and Robin as JLS star Aston Merrygold.
Following the release of the ratings, ITV's Managing Director Kevin Lygo said at the time: "In these testing times, we’re delighted that The Masked Singer has brought some escapist joy and light relief to so many viewers at home.
"At the end of a long week in lockdown we’re all coming together and trying to guess who’s dressed as a giant sausage, and quite frankly, it’s been a brilliantly entertaining tonic."
*The Masked Dancer returns tomorrow at 7.30pm on ITV
