Bone is squirrels brother. He’s is the courageous, curious, fun, and confident sibling. Not like Squirrel, but Squirrel was especially close to her brother Bone. Before he was taken from her he showed her how to take care of herself and start to be more courageous and confident.
Susan is an old woman who finds Squirrel, cold, without comfort and friendship, and starving in her backyard. Susan is a nice women who would really have to like dogs to bring a stray in and spend most of her money on Squirrel. I really like Susan because she was always so nice to Squirrel and in the end Susan and Squirrel who were both old ladies, enjoy the rest of their lives together.
I think things that are different from the characters are bone is confident and courageous and squirrel is not, Susan and Squirrel are almost made for each other but if bone was there he would not have trusted Susan like Squirrel did.som things that are the same about the character is that they all have big hearts and they all loved squirrel.
