Star Bits can be shot at enemies to stun or defeat them but this will deduct from the player's Star Bit total. They also cannot be recovered if fired. In return, using the Star Spin to defeat enemies tends to cause them to drop Star Bits instead of coins.
Star Bits are based on 金平糖 konpeitō, a multicolored Japanese sugar candy. The confectionery has inspired other aspects of Nintendo-published series, such as Gratitude Crystals in The Legend of Zelda and Minior in Pokémon.
