I'm looking for a kids show from the early 2000s that had three, fully costumed characters performing on stage and the live audience being an actual part of the show. They were in mascot costumes, more like Chuck E Cheese than The Wiggles or The Doodlebops, but the designs were almost Jim Henson-esque. I remember it was either just a stage show put on DVD or was on a toddler's network like Sprout or PBS Kids. The last detail I remember was a good night song that would play at the end of each DVD/Episode where it ended with all the characters pretending to fall asleep and trying to get the kids to do the same.

I'm thinking of writing a shorter campaign based on the show Infinity Train but I don't know what system I'd use. I'm looking for a system that would have something similar to the numbers in the show used as an actual mechanic. My first thought was Kids On Bikes or Tales from the Loop but I'd love to hear if there's a system that anyone would think would suit it better.
