Lonley Spider?

While I was running around trying to prove my insane theory I found a pit and I was like CRATER and went down it, then I see a spider called "Lonely Spider" in yellow text, I am confused is this evidence or some random spider. (why cant i post images you insane website)

 

It was part of a quest (Or it is, I don't know if this quest still exist), it drops a red flower for that said quest (Or it dropped, Idk)

If I'm not wrong, now it's just a reference to the quest.

 

It originally was the only mob that could drop a rose with a low chance, thus being vital to completing Bob's Lost Soul. Now there's the Lonely Rose and Peppered Ghost that drop the rose instead, so the Lonely Spider is only there still I think just because they never bothered to remove it.

________________________________

Also all the yellow text represents is that it's a neutral mob meaning if you attack it, then it attacks you just in case you didn't know

 

It was removed, but Mular5 petitioned to have it brought back and got a bunch of votes, so the spider was added again.
