You Won! is a theme in Mother 3 that plays whenever the characters win a battle against a regular enemy.
Victorious...[]
Victorious... is similar to You Won!, except it plays when the characters defeat a boss. The beginning is slightly more melancholic.
Level Up![]
If after the battle, at least one character levels up, this theme plays.
Learned PSI![]
When a character is no longer feverish, they learn a new PSI technique and this small jingle plays.
