Wishy is a shooting star that can be spotted during the evening in the Animal Crossing series. The player can wish upon Wishy and receive a letter the next day signed by the star.
On a night without rain or snow, a shooting star may appear briefly in the sky, making a twinkling sound. When it appears on screen, players, if holding no equipment, can press the A button, and if they are quick enough, they will make a wishing pose while the star sparkles. The next day, they will receive a letter signed Wishy the Star with a random gift attached to it. It will always be a spotlight item from Tom Nook's Store. This can be done in Animal Crossing: Wild World and Animal Crossing: New Leaf only.
Making a constellation makes it easier to see Wishy. When Celeste gives a date of when a constellation can be best seen, the chances of seeing Wishy are increased. In Animal Crossing: New Leaf many Wishies will appear during a Meteor Shower, although only one will grant the player's wish.
