Sprunki Phase 2, the horror mode
In Sprunki lore, Phase 2 is what happens when Black joins the stage: the screen goes dark for a moment, then the whole world comes back transformed. Sprunki Studio does exactly that, and there is a Phase 2 button as well.
The whole cast transforms
The twenty Sprunkis have their own horror artwork, and characters you make get a demonic version automatically: darker colours, red eyes and teeth.
Scary scenes
Every background has a horror version: blood moon and bats, a storm at the beach, dead trees with glowing eyes, a torn concert curtain and more.
Play it with friends
Phase 2 is shared in a world, so when one player drops Black or presses the button, everyone's screen goes dark together.
