River Rapids used to be an obby in Adopt Me!, that had a two-star rating, making it one of the easiest obbies. This obby has been removed from the game. Previously, as a parent, you would earn 7 for completing this obby or 5 as a baby. There was a 45-minute cooldown timer on completion. Other obbies include Pyramid, Shipwreck Bay, Miniworld, and Lost Temple.
This obby was removed from the game in an update.
