Anything Nickelodeon IP worth putting together for a ride like that is 10 years old AT LEAST. Most of the franchises i'd want in the ride (and I think most would) are long gone from Nickelodeon, so it's really not worth it on either end. Spongebob is the only show that has stood the test of time (although it has gotten progressively worse). It would be best to build a ride just off that, but you then have to ask yourself, how much longer is Spongebob going to be around? Nickelodeon has seen much better days. When they cancelled all the game shows, slime time live, and a lot of the cartoons that many of us grew up with (all of which were actually GOOD), the network really just hit the fan.
