How to use team doctor in Pokemon Black and White 2?

The healing ringtone can only be used in battle.

To restore blood to teammates, you can use the egg-laying/milk-drinking skills: the two skills have the same effect

During battle, restore 1/2 of the user's HP.

Outside of battle, give 1/4 of your full HP to your teammates.

In the second week, in the right passage of Qibao City, someone will give you a pink egg. After carrying the round stone to upgrade and evolve into an auspicious egg, you can learn the egg-laying skill at level 16.

Drinking milk can only be learned from large milk cans, which cannot be found in Black and White 2.

There is also a wishing skill, which can be used to restore blood to teammates by immediately replacing them.
