When you get an incoming signal from a child somewhere in the world, press the green button to send them to the Nice list, and the red button to send them to the Naughty list. There is also a little Pause/Play button if you want to have some cool tunes.
Used music from multiple sources, including another Scratch project from me and one from a completely unrelated person. Also from ELO. There's a known bug where the Nice and Naughty lists move out of position, please move them back if you encounter this bug.
