Slow-render only because I don't know how to golf it enough...
u/Undefined

Post on discord and we'll try to golf for you :P
u/JWinslow23

Well, I'm not sure how to golf this further. Most of the real-estate is in the specific values that make the fern work, which I can't encode in a byte-saving way
