well equips are sid's department, but yeah there are some old pets. Eliza Bath was released in Gacha for the first time on dec 6th of 2005. Entertainer Elica was released as a promo pet, with no equip set, so shes kinda hard to release to eTO with nothing. Still if I went through every pet released on other versions to see if it was on eTO, I'd drive my keyboard through my head.
Anyways I added to the content section with general things, I'll probably expand somethings there on Monday when I remove the snow/mint equips stuff.
