How to get 9,999 Stars Head to the door at the bottom right in World 8-4. Help Wario through the spikes, and get him to the water surface. Go in the door and use the "ground pound" by double-jumping above the 3 stars then pressing "Down + B". You should dive below the water surface and defeat 6 squid enemies before coming to a halt, with them revealing 3 big stars and 3 small stars. Swim up and defeat the lone squid and super jump up to a staircase. This time, double jump again and "ground pound" down to the same area again, where you'll defeat the squids there again and gain the stars once more. Now just repeat to get yor 9,999 stars.
