Gobbledigook
Long ago, in a distant time White Dwarf was actually pretty great. It was more than just the glorified catalogue it is now. The White Dwarf of years gone had reviews and articles about non-Games Workshop products, a Letter To The Editor section that took actual criticism, showed off the armies and home-fluff of average joe players, and it even had comics such as Thrud the Barbarian.
Gobbledigook was another such comic which ran in White Dwarf in the late 1980's; it was drawn by artist Bil Sedgewick.
Gobbledigook
Gobbledigook, or Gook for short (oof, might need to not call him that anymore if he reappears), is an unspecified variety of greenskin who appeared in short, usually one-panel comics. Along with his pet squig, Niblitz the two explored and poked fun at Games Workshop properties including Warhammer Fantasy, Rogue Trader, and Blood Bowl. While Thrud tended to mock the universe from within, Gook would break the fourth wall and mock models in our universe by reacting to their ugliness in-universe, cross tables during game sessions and mix the universes up as people chased him, and tease Games Workshop staff. Notably everyone seems to know his name, and those who enjoy ludicrous continuity could fairly conclude he is a 4th dimensional being similar to the DC Comics' Bat-Mite. Some people try to say he may have been a Forest Goblin, but since he doesn't wear a Native American cosplay outfit, this is unlikely. The same people also say evidence of this is Niblitz being "Spider-y", but he looks more like a horned swabsquig.
