“Walrusman” was one of the characters in the cantina scene in the Original Star Wars (that’s Episode IV, youngsters). You may not think you remember him, but here’s a clue. He’s the guy who confronts Luke at the bar and ends up getting his arm cut off by Obi Wan Kenobi. “Walrusman” is a nickname, which may well have been coined by Kenner for purposes of naming their action figure. According to online sources, the character wasn’t given a name, species and backstory in the Star Wars universe until 1989. Officially his species is “Aqualish” and the character’s name was “Ponda Baba”, but I’m just glad we have a walrus tie-in with Star Wars here on the blog.
