Possible Hosts for Nickelodeon's Crystal Maze, From Someone Who Hasn't Watched Nickelodeon in Well Over 15 Years

There's going to be more than a hint of guesswork here as I haven't actively watched Nickelodeon in the UK in a very, very long time. I've no idea who's a current presenter on 99% of the UK network, never mind the US channel making the show, so I apologize beforehand for being ill-informed and just generally wrong and old.
