I think so, because it has only ever appeared when i use this map. He can also spawn into any other maps you play on. if you shoot him a bunch of times hell explode and leave a funny hate comment in the chat. Its name is in Portuguese (Brazil), and last time i checked it translates [incorrectly spelt name to be noted] to "roads key" or something like that

It's also in The entities menu and walking into it will also make it explode
