Mario introduced the participants to his tunnel of doom which was filled with traps. He also reminded them to not die. Wario ran across the tunnel but pressed a button. It summoned a Mini Mario in a cage. Wario thought it was harmless but he was proven wrong when he got attacked. Waluigi nearby saw his brother's presumed demise and laughed it off as he proceeded down the tunnel. He soon encountered a cart on tracks and rode it. A challenge appeared: A target which was required to be hit before access would be granted. Waluigi tried firing at the target twice but it failed both times and instead, a ricochet into stopping the cart, and the releasing of a lantern which set Waluigi on fire. The cart shortly after crashed into the gate and exploded.
