High Dive

High Dive is a new released episode on 20th February for Angry Birds Rio, being the tenth sequential episode. It comes with new water features similar to those in Piglantis, Arctic Eggspedition, and Pig Dipper. It has 20 levels currently. The episode features caged birds that must be freed, however, a new feature includes caged dolphins. These dolphins can be found trapped in cages underwater that are attached to platforms. However, they can be freed as easily as caged birds. Golden Treasure Chests appear as collectibles that behave similar to the Golden Fruits.

Trivia

 * Instead of game sprites, it now introduces toons sprites, which replaces birds from their Angry Birds Google Chrome sprites, which replaced their Angry Birds Original sprites.
 * The Level Failed screen that appears will be different depending on which animal has not been freed. If a caged bird has not been freed, a caged bird will show up on the Level Failed screen. If a caged dolphin has not been freed, a caged dolphin will show up on the Level Failed screen.
