Happy is an emotion available in The Sims 4. It occurs when a Sim performs a positive interaction, succeeds in an interaction or enters a room with wall decorations. Having Happy moodlets will boost the effects of other positive emotions like Flirty, Focused, Inspired, Energized, Playful and Confident.

Interactions and ActivitiesEdit

Sims will only have a chance to use these interactions and do these activities while happy.

Supportive TraitsEdit


"Happy" can evolve into "Very Happy".

These traits affect how often a Sim is happy.
  • Cheerful
  • Sims that Love Outdoors will become Happy when outside.
  • Good Sims will become Happy when around Sims feeling positive emotions.
  • Evil Sims will become Happy when around Sims with negative emotions.
  • Bros become Happy when around other Bros.

Object AurasEdit

These are items found, bought, or earned in the game that can emit a happy aura in the area around the object. Players can choose to enable or disable the aura at any time. Once enabled, a Sim can interact with the object, through viewing or using it, and they will earn a happy moodlet. Whether their mood changes to happy or not depends on the other moodlets affecting the Sim at that time.


Happy Sims may get the following whims:

  • Dance to Stereo

  • Call Someone on the Phone
  • Chat with Someone
  • Tell a Joke
  • Meet Someone New
