Rhubarb's Links
While he might just seem like a big fuzzy crow, Rhubarb is Sam's best friend. He loves her very much and would do anything for her. He understands her clearly, and knows she understands his caws and squawks, too.
Sam loves Rhubarb almost like a brother, and would do anything to keep him happy and healthy. The two are the best of friends, and are rarely seen apart.
