Here's what happens:
* The music box grants you access to the Wishing Well. This well is a special location where you can:
* Wish for things: These wishes usually involve helpful items or abilities for your exploration.
* Change your team's formation: You can rearrange the order of your team members.
* Access the "Wishing Well Store": Here you can purchase items that have been requested by other Pokémon who've visited the well.
* The music box itself is now a permanent fixture in your den. It's always available for you to use to return to the Wishing Well.
The Wishing Well is a vital part of the gameplay in Blue Rescue Team. It allows you to gain a strategic advantage and unlock new possibilities as you progress through the game.
