The Masked Singer UK season 4 shares first look at crazy new costumes

Ready to blow us all out the water - it's Otter!

Judge Mo Gilligan says Otter is one of his favourite characters this season: "I love otters, one of my favourite animals. Otters have a stone that they have to smash clams, so ours has little pockets for the stones on the costume. The attention to detail and the costumes are so cool."

They’re feline good – it's Cat and Mouse.

Judge Davina McCall says it's more difficult to guess the identities of a duo like Cat and Mouse: "It's funny because you'd think, 'Oh. Well, there's two of them. If they're a duo, then it's easier to guess'. But I've been looking at them thinking, 'You're not a couple,' but then they might be acting like they are a couple."

Could this be history in the baking ? It's Piece of Cake!

This bird's on fire – it's Phoenix!

Judge Mo Gillian says some celebrities try to make it more difficult for the judges to guess their true identities: "I feel people are really coming into their costumes more this series. So Phoenix always looks at us a bit weirdly for example. Then you've got some characters who are really funny, which is also hard because you think – is this a comedian that I know?

"And you can always see in the room who's a fan favourite as well. It isn't a singing competition is it, it's just guessing who's behind the mask! I think that's my favourite bit where they sing and you start seeing the little kids reacting like, 'Who should we save?' And kids are screaming names out, which is one of my favourite parts of the show because some of the kids don't even know some of the guesses we've said. The 7-year-old, he's shaking their head at a guess!"

Ghouls just want to have fun – it's Ghost!

It must be dove – it's Pigeon!

Their singing is sure to butter you up – it's Jacket Potato!

This character is another of Mo Gilligan's favourites: "Probably this series, my favourite costume is Jacket Potato, it's so weird! You've even got styrofoam feet that you get for jacket potatoes. And you just look at it and the attention to detail is insane, he's got a shirt which is beans and there is butter on his head."

They only sing when they're stinging – it's Jellyfish!

Judge Rita Ora named Jellyfish as one of the performers that's blown her away so far, saying: "I think the characters I’m really drawn towards are Jellyfish and Rhino. And some of them really make me laugh, like Otter. Those three are the ones that stand out most to me."

There's no time to waste – it's Rubbish!

They were horn this way – it's Rhino!

Davina McCall admitted that Rhino's performance has made her cry: "Rhino has been particularly emotive. There are people who completely draw you in.

"It’s lucky for Rhino, actually, that they can pull some emotion out of the bag, because it's very, very hard in that costume to give us anything at all. They are massive, and they are quite humble.

"They keep putting their little hooves together, it looks so sweet. If it's possible to have a sweet rhino, this is it."

Leaving the competition in knots – it's Knitting!
