A Red Ring is a ring, appearing in the New Super Mario Bros. series, that when jumped through or touched triggers eight hard to reach Red Coins. Usually they'll be hard to get, since when you collect all eight, a random power up (usually a Fire Flower), or 1-up mushroom appears over each playing character's head. If in a bubble during multiplayer you will not receive an item. In New Super Mario Bros. 2 similar rings called Gold Rings that turn most enemies in a level golden (golden enemies award escalating sums of coins when defeated) appear, and Green Rings in New Super Mario Bros. U and New Super Luigi U make five bunches of three green coins appear, but these must be collected in a certain order.
