Adventure Island 3 (NES) - Area 2-3
After seeing a penguin at the start, watch for icicles falling from the ceiling. If an icicle rattles, that means that it will fall, so be sure to keep your distance. After seeing a walrus for the first time, the egg ahead contains a card that gives off the blue dinosaur. After a dangerous path, go past one more penguin and you’ll reach the goal.
