Pokemon Happiness

Each Pokemon has a hidden statistic called happiness or friendship that can range from 0 to 255. Happiness is used to make some species of Pokemon evolve and to calculate damage for the moves Return and Frustration.

A Pokemon’s happiness is tied to a specific trainer so if a Pokemon is received from a trade, its happiness will be equal to the Pokemon’s base happiness. If a Pokemon is traded back to a trainer that had traded it away, the happiness returns to its former amount before being traded.

Checking Happiness

The best way to find out your Pokemon's happiness is to talk to the lady in Konikoni City next to the TM shop. She will say different things depending on your Pokemon's current level of happiness:

My! It feels incredibly close to you! Nothing makes it happier than being with you!250-255
You clearly love your Pokémon, and you must spend a lot of time together.200-249
Hm. I’d say that you and Pokémon have the potential to be an even greater combo.150-199
Hmmm. I think...it feels friendly toward you. At least a little...100-149
Hmmm... I’d say that you and your Pokémon still have a long way to go.50-99
What is going on here? Do you let it get knocked out a lot in battles or something? This is bad.1-49
Oh dear. You must be a merciless Trainer... Do you use Frustration or just not know better?0

Another way to find out about your Pokemon's happiness is to put your Pokemon into the hot springs at Isle Avue on Poke Pelago. Mohn can also give you information about your Pokemon's happiness.

Increasing Happiness

When a Pokemon is caught or first received from a trade, its happiness is usually equal to the Pokemon’s base happiness. Catching the Pokemon in a Friend Ball means that it starts out with 200 happiness instead. Additionally, hatched Pokemon will always start off with a happiness value of 120.

Several things can be done to increase (or decrease) a Pokemon's happiness. Depending on the Pokemon's current level of happiness, the effect of these activities can vary. Additionally, if a Pokemon was caught in a Luxury Ball or is holding a Soothe Bell, all increases to happiness are doubled.

Fainting in Battle-1-1-1

There are also two other places to increase your Pokemon's friendship but the exact amounts are currently unkown. First of all, in Festival Plaza, meals at the Friendship Cafe and Friendship Parlor can increase friendship. Secondly, leaving your Pokemon into the hot springs at Isle Avue on Poke Pelago can also affect happiness but the exact amounts are currently unknown.

A final think to note is that the massage therapist at Konikoni City will only give one massage per day so use it wisely!
