Furry Frolickers is a term used to describe a group of animals that are known for their playful and mischievous behavior. In this case, the term is referring to otters, which are semi-aquatic mammals that live in rivers, lakes, and oceans. They are known for their playful nature, often seen sliding down muddy banks, chasing each other, and playing with rocks and sticks. Otters are also very social animals, living in large groups called rafts.
