It sounds like you may have been in the EU region of PlayStation Home.
Maybe it´s a "normal" thing, but i rarely go to Playstation Home but today i walk there and i notice an giant robot on sea.
I´m curious. Whats the meaning?
There is currently a promotion for the movie Pacific Rim happening in Home Square which involves giant mech suits battling giant monsters. (In the sea)
You should try it out, it's a fun and interactive game and you get an interesting reward for participating as well.
Thats it Legofire! hehe
I´m from Portugal
I found a video with that:
Very nice, I hope you enjoy the event.
