I'm not really up to date on what the kids are watching these days (once you hit 25 it's all downhill from there) but supposedly this Phineas and Ferb: Across the 2nd Dimension
thing is pretty popular on that there Disney Channel. The game just his shelves and there's a launch trailer to go with it, describing a few of the things you might do in said 2nd dimension. One would imagine that in the 2nd dimension all you'd do is spend a lot of time being 2-dimensional, but it shows what a geezer like me knows. Doesn't anyone remember Dexter's Laboratory anymore?
