While the book has already established a connection between Wash and the octopus, Tanna’s connection to it is just as revealing. She likes the octopus for its intelligence, but also because of its adaptability. This is particularly salient for Tanna, as she often feels like an outsider in English society because she is mixed-race. Therefore, she would be able to avoid people’s racist assumptions if she could adapt her appearance like an octopus.
