Red Rings are objects that appear in New Super Mario Bros. When you touch them, Red Coins appear. If you collect all 8 Red Coins, you get a power-up depending which form Mario is:
- If you are Standard Mario or Mini Mario, you get Super Mushroom.
- If you are Super Mario, you get Fire Flower.
- If you are Shell Mario or Fire Mario, you get 1-Up Mushroom.
- If you are new at playing this, they are quite hard to collect at first.
