The supreme thingy would be called an "Easter egg"(something left behind to be discovered by others). I like it,I was thinking maybe make a game out of it(like Simon says) but you have to mix everything in the right order exactly(like green slurpie, orange, green, blue, blue...ect) and if you hit x(say 20) the Easter egg is complete after you put the slurpie in the hole and a chest floats through the ground.
