The mystery person also referenced having an alter ego and said there was more than one of them to know.
Following the clues, fans of the ITV guessing game show are convinced they know who is behind the mask and they believe former Little Mix star Jesy Nelson could be the one dressed up as the Jellyfish.

In their clue package, they said they were "all about the love" and revealed they had "won unexpectedly before".
"Hey it's me, Jellyfish! Welcome to my beach! Jellyfish are transparent. They're blessed. What you see is what you get," they said, "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."
Guesses for Jellyfish have included Glee star Amber Riley whilst others think it could be Michelle Visage or Kym Marsh.
