Say, do you know the old licensed cartoon The Real Ghostbusters? You'd probably like the episode Who're You Calling 2-Dimensional, in which they get stuck in a cartoon world, and maybe the less-good but still interesting Stay Tooned, where a tv character transforms real New York into a cartoon
I remember seeing "Stay Tooned" but I guess I missed out on "Who're You Calling 2-Dimensional". I'll have to look that one up. Thanks for the recommendation <3
