As a Pokémon expert, I can tell you that Pichu evolves into Pikachu when it gains a certain level of happiness and trust with its trainer. The specific level at which this happens is not defined by a specific level number, but rather by the happiness level of the Pichu.

To increase a Pichu's happiness, you can:


1. Play with it to build a bond.

2. Feed it berries that you can find in the wild or purchase from Poké Marts.

3. Avoid letting it faint in battles, as this can decrease its happiness.

Once Pichu's happiness is high enough, it will evolve into Pikachu the next time it gains a level through experience points, which can be earned by battling other Pokémon.
