When determining your character’s ability scores, increase one score by 2 and increase a different score by 1, or increase three different scores by 1. Follow this rule regardless of the method you use to determine the scores, such as rolling or point buy. The “Quick Build” section for your character’s class offers suggestions on which scores to increase. You can follow those suggestions or ignore them, but you can’t raise any of your scores above 20.

You are a Humanoid

You are small

Your walking speed is 30ft

Your beak is a natural weapon, which you can use to make unarmed strikes. If you hit with it, you deal piercing damage equal to 1d6 + your Strength modifier, instead of the bludgeoning damage normal for an unarmed strike.

Your hide is well insulated from living in the harsh cold of your native lands. You are resistant to cold damage.

You are naturally adapted to cold climates, as described in chapter 5 of the Dungeon Master's Guide, can cross icy surfaces without needing to make an ability check. Additionally, difficult terrain composed of snow or ice doesn't cost extra movement for you.

You have a swimming speed equal to your walking speed, and you can hold your breath for up to 15 minutes, even in Icy Water.

Penguins slide on their bellies because they have short, thick and dense feet, which makes it hard to walk. They use their sleek bellies while pushing their feet. This method is called "Tobogganing" to slide on their stomachs when they want to move quickly while conserving energy.

While not wearing armor, you can slide over non-rough or wet surfaces such as snow, ice, or a polished floor, but not uphill. Once per turn, if you move at least 10 ft. in a straight line, you can spend an additional 10 ft. of movement to slide in a straight line a number of feet equal to your move speed. If you use an action or bonus action while sliding, your movement speed reduces to 0 for the rest of the turn and your slide is interrupted.

This movement does not provoke any type of attack of opportunity and can freely move through any spaces occupied by a creature one size larger than you. You can continue the slide on subsequent turns as a free action a distance equal to double your movement if you are sliding downhill.
