Jughead makes it yet another character from the Archie universe, and you can only unlock him by playing as Archie. Keep hopping till you see burgers (Jughead’s favorite food) on the side of the road. Don’t just eat one of the burgers – you may have to eat up to thirty until you’ll be notified that you have successfully unlocked Jughead, and can play as him on your next game.
Based on the character’s name, Michael Boom is obviously a reference to director Michael Bay, who’s become well-known (or, for many, notorious) for his explosion-filled movies. You’ll have to be playing as one of the new characters introduced through the Archie update in order to unlock Michael Boom, and you’ll also be required to keep hopping till you see the big green truck with a rocket. Hitting the rocket would cause a huge explosion, killing you in the process, but the tradeoff here would be Michael Boom himself.
Last, but not least, we have the Rugby Player, and you’ll have to play as a UK-based character to unlock this dude. Hop till you see a rugby ball in a tree, and once you’ve gone past the rugby ball, you can play as the Rugby Player after your next game over.
