Penguin surfing? How to add to a character?

[YetiCake98]

So i have a question and i want help. Ive been planning on making a character lately for Don't Starve (and the DLCS once i figure out the basics)


How would i code a character to do a brief animation-(or a prolonged one) where they slide on their belly to move faster across the Constant/Don't starve world?

Im making a penguin character essentially and i was wanting to know how i'd go about that.
