Happiness

"Happiness" is an in-game mechanic that indicates how friendly the Pokémon is to the owner, from a scale of 0 to 255. A Pokémon's Happiness is seen as a percentage in its summary, on the party screen, or when hovering over it when viewing Fields.

Effects

Evolution

There are Pokémon that require a certain amount of Happiness to evolve.

There are currently 21 Pokémon that evolve from having high Happiness. In order to evolve, the Pokémon must have a Happiness of 220 or more.

There are currently 2 Pokémon that evolve from having 0 Happiness. Due to rounding, the Happiness percentage may show 0% even when the Pokémon has more Happiness.

Raising Happiness

Fields

If a Pokémon is put into a field that matches or is supereffective against their type, they will gain Happiness. For example, Espeon, a Psychic type, will like the Psychic, Bug, Ghost, and Dark fields. Since Espeon matches the Psychic type, its Happiness will increase faster in a Psychic field than in a Bug, Ghost, or Dark field.

Pokémon that are busy, such as Pokémon in the DayCare, will not gain or lose happiness from fields.

Consumables

Certain Consumables can be used to raise happiness.

• Cookies were obtainable from the Valentine's Event.
• Sweet Hearts were obtainable from the Valentine's Event.
• Easter Eggs were obtainable from the Easter Event.
• Lovely Soups were obtainable from the 2019 Valentine's Event.

Trading

Trading resets a Pokémon's Happiness to 70. This can be used to restore a Pokémon's low Happiness, but can also lower a Pokémon's Happiness if it is higher than 70.

Lowering Happiness

Fields

If a Pokémon is put into a field that is not very effective against their type, they will lose Happiness. For example, Umbreon, a Dark type, will dislike the Psychic and Ghost fields. Since Umbreon completely resists the Psychic type, its Happiness will decrease faster in a Psychic field than in a Ghost field.

Pokémon that are busy, such as Pokémon in the DayCare, will not gain or lose happiness from fields.

Gigaremo

Use of the Red Gigaremo will reduce the happiness of both Pokémon in the Daycare while increasing the number of eggs bred. If Happiness runs low, the pair's breeding rate is decreased until their Happiness is restored. At 0 Happiness, Pokémon will refuse to produce eggs.
