In Pokemon red rescue team do you actually use the music box when mew is in front of you?

You do not use the Music Box on Mew in Pokemon Red Rescue Team.

The Music Box is used to calm down a certain type of Pokemon that is affected by the Curse of Darkness. This is not the case with Mew.

Here's how you encounter Mew in Pokemon Red Rescue Team:

1. Complete the game: You must finish the main storyline of Pokemon Red Rescue Team.

2. Talk to the old man: After the credits roll, you can talk to the old man at the entrance to the Great Tree.

3. Get a new mission: He gives you a mission to save a rare Pokemon in the Great Tree.

4. Find Mew: Mew is hiding somewhere in the Great Tree, and you need to find it.

5. Catch Mew: Once you find Mew, you can attempt to catch it.

Mew is not affected by the Curse of Darkness, so the Music Box has no effect on it.
