The Awakened goose always seems mad. Insight rolls against the goose are made with disadvantage due to it's angry demeanor.

With it's anger, the Awakened Goose can use it's beak to bite and can rage as a reaction when attacked. The goose can not use his beak to make an unarmed attack if the goose is currently holding a weapon.

The goose is naturally good at Charisma (due to it's terrifying nature) and strength.

The Awakened Goose can read and understand any spoken language it knows, but it can't wrap it's tongue around languages other than it's own.

When speaking, if the goose shares a language with the target, the target can understand the general gist of what the goose is saying, though perhaps not the exact phrasing. Due to the lack of exact understanding, the goose is proficient in deception.
