Snugglers are a type of nestler, which is an animal that builds nests or shelters for itself and its young. Snugglers are typically small animals such as birds, rodents, and marsupials, that build nests out of twigs, grass, and other materials to protect their young from the elements. They often use their own fur or feathers to line the nest and keep their young warm. Snugglers are important to the environment as they help to maintain healthy ecosystems by providing food and shelter for other animals.
