If you add Theivul, you can have four darkie cookies. Five with Umbreon, but she would be too small, a full six stack with Zorark, but we are way out of theme at this point.
Going back to the core three and Theivul, you can add Liepard for 5 medium-sized (Non-sphere headed) darkie quadrupeds, but then you lose the cookie theme.
...but again going back to just Theivul and the core three, Nintailes and Lycanroc (Day) have dex descriptions that point to them as being evil, but then you run into the problem of Absol not being implied as evil outside of being a darkie.
