As pointed out by Club Penguin Blogger Saraapril today, the Disney UK Club Penguin page has been updated with some bits of information about the party.
The page reads:
Adventure Party: Temple of Fruit – UNLOCK THE MYSTERY!
Avast! Our favourite pirate, Captain Rockhopper, has brought tons of fruit, new adventures and a hungry volcano idol to Club Penguin island.
Everyone can collect fruit to feed the volcano, and member penguins can set off on a scavenger hunt to find fruity new costumes.
At the end of week one, after working hard to appease the volcano’s hunger, the new Smoothie Smash game will be unlocked in the three fruit room areas. After the party it will take its place permanently in the Coffee Shop – giving penguins a healthy alternative to the Coffee Shop’s regular fare.
