on the hide-and-seek minigame, the optimal strategy is to hide behind the springy horses. Because they don't actually hide your character, the person guessing knows nobody is hiding there, and thus will never guess there, meaning they have 5 guesses to search the 6 remaining hiding places. With three people hiding, there's only a 50% chance of winning if everyone picks different hiding places, which doesn't usually happen. If you hide behind the springy horses, the person guessing needs to waste one guess on those, meaning they only have 4 guesses to search the 6 remaining hiding places. As long as the 2 people hiding don't pick the same spot, that gives you 67% chance of winning
