HABBES
Meet Habbes, an exhilarating cryptocurrency token that draws inspiration from Hobbes, the beloved Yorkie of Elon Musk, who shared Musk’s life for an astonishing 15 years. 
Habbes is Hobbes’s girlfriend and, like him, is described as “nasty, brutish, and short.” This spirited dog won Hobbes’s heart with her resilient and unyielding demeanor.
