The term 'bushy-tailed rodent' refers to three different animals: the SQUIRREL (8 letters), the MARMOT (6 letters), and the CHINCHILLA (10 letters). Squirrels are small rodents with long, bushy tails that are found in many parts of the world. Marmots are large ground squirrels native to North America and Europe, and they have thick fur and long bushy tails. Chinchillas are small rodents native to South America, and they have very dense fur and long bushy tails.
