Warthog

The Warthog is a passive creature that is approximately the same size and shape as QQ, Gust's pet pig, though the wild boar has large tusks, a mane of off-white fur, and darker skin than QQ. It likes Fireflies.

The warthog can be talked to, but it does not have any interaction options and cannot be befriended or adopted.

Unlocking
The warthog is introduced in  Chasing the Light and can be found near the player's house during the mission.

After completing the mission, it can be found harmlessly wandering around near the Portia Harbor.

Trivia

 * The same creature appears in a currently unimplemented mission,  Save the Warthog.
 * The Warthog can also be seen on the late evening of Summer 12 where it walks around Peach Plaza. It proceeds to the area in front of the player's gate. The player can interact with the Warthog but it is not possible to talk to it or to gift it anything.
