Shrek-n-Roll

On each level of a vs. game there will be some potions, usually 2 of them. To start a dronkey attack you need to pick up the potion like you would a coin. Since there are only 2 per level, you'll have to advance to the next level to get a third (this counts as the same game).

Easily done with a lcoal boosting account and a second controller.
