One take from discussions on Millscord was that on Albert Stink is that he suddenly woke up on the pitcher's mound right next to the fax machine as a stink bug puppet, in a Kafkaesque manner. He is deeply interested in existential philosophy.
Another major interpretation of the character is that he is a Pangolin.
There has been an attempt to reconcile the two by stating that every day Stink may appear in a number of forms, but his most famous forms are the stinkbug and the pangolin.
