Boss guide

Dr. Robotnik sits in his Egg Mobile attached to a weak beam at the top of the screen, but he hardly does much except drop a few harmless bombs down while the player is thrown around inside the pinball section. The real challenge here is actually reaching Robotnik's territory, while avoiding traps such as retracting spikes, spheres, and other various traps. At the bottom of the table, above the bottom two flippers, there are three lights and a roller. Touching the roller turns a light on. When all three are on, a platform folds down stopping the player from falling onto the slotting spikes, but touching the roller again resets the lights. If the player follows the correct path of springs, they will reach Robotnik, where all that is required is to jump through the blockades while panels appear to make sure the player does not fall back down to the pinball section, until reaching the next ground level where the doctor flies away on his Egg Mobile.
