Jellyfish is one of the colourful characters taking part in this year's show, but who could it be under the mask?
Who is Jellyfish?
Jellyfish performs Alone by Heart on The Masked Singer UK
Clues so far:
"Hey it's me, Jellyfish! Welcome to my beach! Jellyfish are transparent. They're blessed. What you see is what you get.
"But we're also bio-luminescent. Isn't that a bodacious word? It means that we create our own lights and that's me. I'm all about the love.
"In fact, I'm an advocate for it. I'm here to shine bright and have a good time. And if I win, well I won unexpectedly before. Tonight, will I sink or swim? All I'm saying is you better get ready for this jelly."
"Give me good vibes only, that's a great salutation. Let's love and not hate, like a funny animation."
