"Kayna wants to play a game! The Fire Elemental has given each of its new monster friends on Tribal Island a piece of a puzzle, and it's up to you, the My Singing Monsters community, to put it together!

Different players from different countries will receive different pieces, so when you get a piece in your game, take a screenshot and post to Facebook or Twitter with ‪#‎MSMPuzzle‬ so you can figure out the puzzle together!"

That makes it sound like a 30-31 piece puzzle (depending on whether Kayna give a piece as well)
