Cubchoo dashes forward the moment it sees food. It will pause to breathe a freezing gust of wind onto the berries before beginning to chow down. ...Italian ice.

Cubchoo has no idea what the 'city' is but if there are nice things there like her it would definitely be better than staying in this place. It's OK if she can't bring it home. It thinks she would probably freeze and die, and even if they just met, it doesn't want her to freeze and die. And if she does freeze and die the Beartic would probably eat her and that would make it sad.
