What scent do you associate with, ( I did what first came to my mind xD These are pretty weird. EDIT: Oops up from Greg I did sound.)
Garnet: Blood ( Idk.. )
Pearl: Chalk ( Back to school? )
Amethyst: Snow ( Let me make this clear, Amethyst is the FEBRUARY birthstone, and in Canada it's ALWAYS snowy in February. Guess where I live, Canada. )
Steven: Roses ( Because of Mrs. Rose Quartz.... )
Lion: Marshmallows ( Dat fluffy mane! ^-^ )
Greg: A music band practicing ( Music, get it? Get itttt? )
(EDIT: Shoe Box Smell ( Idk my ideas of Garnet and Greg... ))
Lapis: Water leaking from public and dirty pipe ( Because I do not like her and I do not like public water fountains very much. )
(EDIT: Chlorine ( Chlorine makes me sneeze and makes my eyes hurt, kinda like Lapis

))
Peridot: The sound of Rain ( Because of When It Rains, my favorite episode, and I love rain and my birthstone baby Peridot. )
(EDIT: Wet Grass ( Wet Grass comes when it rains, and I love rain, and that episode, Screeeeeeee! ))
Jasper: Gems Cracking ( .. I'm sorry, shes my baby but still evil. )
(EDIT: Wet Dog ( Hm, I guess this one is because, wait, do the events of Beta and Earthlings count as spoilers? I'll just put it in transparent. [
I think this was the first thing I thought because her corrupted form looked very canine to me. ] ))
