Noodle

Noodle is one of the eight dogs you can adopt at the beginning of the game. When you first meet Noodle, he is curled up on the ground. Your musher says that he doesn't like indecision, and decided what to do if his musher didn't.

Noodle's Quest
When you hear a wolf howling, Noodle howls back, and your character asks if Noodle is trying to scare it off or bring it closer. If you choose to follow Noodle, he will lead you to a wolf with its leg stuck in a rusty trap. If you free the wolf, the trap will fall apart. At camp, petting Noodle will progress his story.

Later, you hear the wolf howl again. Following it will show you that the wolf has killed a caribou as thanks for releasing it. Text will appear saying Noodle thanks you for listening. Petting Noodle is required after this event to get the next one.

Near the cabin, the wolf will appear again at the side of the trail, and you can let Noodle take a break to play with it. This will complete Noodle's story.

Noodle's Abilities
Every run after completing his story, you can encounter the wolf again, who will give you food whether or not you have freed it during that run.

Noodle can also help you decide whether an encounter is worth going into.
