In the final level of each island or chapter, you will receive the objective to free the Languini.
The Languini will be placed on the game board in place of a colored tile. To complete the objective and free the Languini, you must make matches and remove tiles that bring the Languini to the bottom of the board.
Once you complete all levels on an island or in a chapter, the Languini is finally rescued. This is indicated by unlocking the Languini’s character card that can be viewed in the Collection.
