The term COMFY PLACES can be broken down into two crossword solutions: DENS (4 letters) and NESTS (5 letters). DENS are typically small, enclosed spaces that provide shelter and protection from the elements. They are often found in nature, such as those built by animals like foxes and badgers. NESTS are also small, enclosed spaces, but they are specifically designed for birds to lay their eggs and raise their young. They are usually made of twigs, grass, and other materials, and are often found in trees or on the ground. Both DENS and nests provide a comfortable and safe environment for their inhabitants.
