The Slimcat is back! Originally awarded from the Fates of the Shadowlands Raids achievement during the Fated Shadowlands season, it appears that players who missed obtaining Jigglesworth, Sr.
can purchase the mount with 3 Antique Bronze Bullion (dinar) in Dragonflight Season 4!
The mount is sold by one of the four new Awakened vendors on the Season 4 PTR, and is the only item sold for three bullion, while other cosmetic appearances require one and raid gear costs two each.
All four vendors can be found in the Parting Glass, on the east side of Valdrakken.
