Trying to think what a peanuts and Scooby-Doo crossover would even be. Mystery Inc are teens, so would they talk like trombones? Would they maybe only sometimes have trombone voice when they went overly elaborate (velma and fred would be most likely for that)? How would they stylize it? Everyone in one style, or each series in its own like the courage scooby crossover. What could even be a plot that woudl justify this
