In Monopoly GO, there's a fun event called Mermaid Treasures where you need special pickaxes to find hidden treasures.
The best way to get lots of pickaxes is to play special events and tournaments because you can win lots of cool stuff!
You can also get a few extra pickaxes by completing daily tasks and opening free gifts in the shop.
Sometimes there are special links that give you free pickaxes, so keep an eye out for those!
