The fishy robloxian

Hello. I am, once again, Likemea. This day, i was normally playing Roblox, my favourite game. But, of course, something strange happened. Otherwise, why would I be here? Anyways, I was on the home page where I saw an advertisement to the left of my screen. It said:

 F1SHYROBL0XIAN entered.

I had never heard of this guy before! On the advertisement, the text was in red, and the background was blue. This was very unappealing to the eyes. Anyways, I clicked on the advertisement. It redirected me to a page with a group called 'F1SHY SLAVES'. Everyone on that group said on the wall, 'THIS ISN'T FISHY AT ALL'. I looked on the people in the group, and it said 13 people were in the section 'MINE NOW'. There was also the owner, which was F1SHYROBL0XIAN. I tried to join the group to see what was going on. However, a message popped up. It said this:

'I AM F1SHYROBL0XIAN. YOU ARE NOT FISHY. PLEASE LEAVE.'

I tried again and again, but this guy F1SHYROBL0XIAN was quite a bit protective. Anyways, I decided to go back to my home page. For some reason, all the text on my home page was in morse code. What had happened? Maybe this F1SHYROBL0XIAN was playing games with me. I translated the text that usually said my name, and it said 'LoOk BeHiNd YUUU!'. So, something was not okay.

F1SHYROBL0XIAN knew something about my life. He knew something about me. This was true, because when I looked behind me, there was a door that was never there before. Okay, now what?
