If it would only count as a memecategory, then I might as well sugest a similar category, where you have to collect 25 apples on yin-yang mode only using the reversed snake.

All of the categories so far for Google Snake have been "Eat 25 apples" "Eat 100 apples" and so on, but I have an idea for a slightly unorthodox category for Sokoban 5 apple mode. My idea is to see how fast you can open all 5 boxes without eating the fruit inside. The run would end when there are five fruit fully visible onscreen.
