this guy doesn't really qualify for the gene splice trait as their genes aren't really spliced with thistlehoof dna. they are really just a horse - sorry for tricking you all with that one! here's the real trait list:
trait list: wrote:[nr] custom lines, weight edit, edited bell, edited tartan
[s] no udder
[c] short hair edit, switch edit, no horns
[uc] smooth fur, tail edit (other), ear edit, snout adjustment
[r] back mane, hoof edits
despite being an april fools gag, this adopt does actually come with an announcement. the new edited tartan trait! this trait is a non-rarity trait that allows for edited tartan appearances (such as saddles, harnesses and other collar shapes), though they should still have your barns tartan pattern somewhere.
with that sorted, the winner is ArithMedic! congrats on your first "thistlehoof" ^^ ill add your tartan in a bit.
