Welllll alright lemme explain this before I mess this up again
Legs 1-2 are by Alt_Ikmoj, so go see his 2 legs before going to mine.
Those eliminated in Ikmoj's legs-- you can delete. If you're lazy and don't feel like doing that:
I just re-created legs 1-2, automatically eliminating 2, so then you should be ready to go!
