put the ladder in the first bubble maker. then when they all collect the nerds put the ladder in the little cove against the wall when they go in the second bubble maker move the ramp on the left side of the machine so they can drop off their candy and then turn around to pick it up. then move the ramp and let them go in the second bubble maker again so the could float to the top secret room. that's all tell me how it goes for you xxxoo
