Some online fan manga that apparently hasn't been updated in ages. It's called Monster's Territory (怪獣占有領域 "Monster-Occupied Territory") and it's made by Nanamatsu, one of the guys that worked on that awesome fan-made suit from last year. Godzilla fights a fan monster called Raia and it ends on a cliffhanger after three chapters, presumably never to be resolved.
Worth checking out if you're interesed in Godzilla doujin, I assume. Be warned though, it's mostly "people scenes".
Also, apparently the Japanese version of "skreeonk" is "Gaguoooooooooooo".
