Azulin is a blue bear with a prosthetic mask who is the younger twin brother of his elder brother, Tubby. While Tubby was nice albeit clumsy, Azulin was mean and driven by envy how his mother always preferred Tubby compared to him. Due to his obsessive, arrogant, and rather questionable nature, Azulin is not very liked by his peers. Despite this, Azulin can act very innocent and is a magnificent actor, for a bear that is. most of the time he’s cold, obsessive, and rather stalker-ish.
