This lemon was on our lemon tree for a while, but my uncle picked it up and I took a photo of it. I know there are weirder lemons than this but, are you surprised?
Plant Biology is far from my expertise (as I only scraped by in the general portion of the course that covered it *cough*), but they are still suspect to mutation/genetic disorders, and Cthulemon's maternal-effect genes might be jumbled up.
@MrDayCee Is there a personal nuclear bunker!? Run away from those abominations! Everything is contaminated! *Puts on 5 hazard suits and locks self in a container*

No. Plants have very simple structural requirements, so there are relatively few biological constraints on how they can grow. The only macroscopic features important for a lemon fruit are its seeds, overall size, and colouration, and two of those can be ignored for cultivated plants. Plants also tend to copy certain genes several times over to increase transcription efficiency, so the opportunity for a slip-up is much greater.
That's actually a very common cole sort called Romanesco Broccoli and it always grows like this.
Yes, because the bizarre appearance of this particular mutant gives it a good market value. All of the most common cabbage crops are actually severely deformed versions of wild cabbage.
