[TOMT][Video Game][00s] PC Game with Skeletons/Treasure Island/Skull Island?

My mom used to play this game when I was a kid, so it would be around early 2000s definitely before 2010 but could have come out in the 90s. Was a computer game she had to download onto her desktop, was a match 4 game with skeletons dressed up like pirates. There would be checkpoints I think where if you reached it all the skeletons would start dancing? It definitely had something to do with jewels and treasure, themed around pirates. I remember the skeletons having pirate hats and there being a little map where you would move from checkpoint to checkpoint.
