Much like the humpback, Rollback whales are known for their large size and peculiar shape when compared to other mammalia. Their main habitat is Wal Mart, where roll back prices are abundant. Too large to move under their own power they rely on small electronically powered vehicles to move them about the store.

Solarpunk is a movement focused on a positive, ecological vision for a future where technology is used for human-centric and ecocentric purposes. It is a literary, artistic and aesthetic sub-genre and is also closely tied to eco-political activism. Solarpunk narratives have a distinctly positive and utopian foundation in contrast to the often dystopian visions found within other "punk" science fiction genres.
