Club Penguin: Puffle Wild was a match-3 game released only for iOS back in 2014 based on the online MMO of the same name (Club Penguin) with gameplay similar to that of Candy Crush.
In the game, the player could unlock Puffle Creatures to take care of them in the online game, which is no longer possible due to the online game's shutdown in 2017.
The game was then delisted from the App Store on September 2, 2015, about two years before the actual online game shut down.
