The Darkness

the darkness is from an animated pilot for a show called Learning with Pibby where Pibby and her friend Bun Bun get their home invaded by a black glitch substance that uses popular memes and emojis as its vessels. It invades other cartoons and turns the characters into wide-smiling, glitchy zombies. You are a character in Learning with Pibby and you go to warn Pibby and Bun Bun about the darkness.
