What's the hardest kids' game show bonus round?

I would have to say the hardest bonus round on a kids game show would be the Olmec's Temple bonus round from Nickelodeon's Legends Of The Hidden Temple and I can see why few teams of kids won the bonus round on that show. Besides having to solve puzzles it was very easy for the temple guards to catch the contestants just before they could get the prize. If Nickelodeon could've redesigned the Olmec's Temple bonus round on Legends Of The Hidden Temple the teams of contestants would've had better chances of winning
