So, after I discovered the "boss" form of the lichens, I replayed the quest level over and over again just to be able to get a screenshot of it.
It would go figure that - on the level I do manage to get it to merge - I also encounter a genuine rare mob (I think the first I've seen since I started playing).
And of course, I sat there giggling for far too long while I imagined my character running from it with a bomb held over her head, and it bouncing after her going, "Oi! Halt! Dunneh y'want a spot o' tea!?" Or something else crazy like that. :P
I may even draw a fanart of this... it's a fairly vivid mental image. :P

I encourage you to do so. And welcome to the forums. =P
