Enemies that are like other enemies except they are a little bit different

In Dark Souls 3, there are enemies that are like other enemies but a bit different. I'd call them mini-mini bosses, here is a (probably) full list of them, in no particular order.

Pregnant dog - A dog in road of sacrifices down in the cave with Morne's ring and Carim braille tome. It's belly is big, therefore it can be assumed it's pregnant. It also has a grab attack.

Peaceful deacon - A deacon in cathedral of the deep that resides on a tower near the entrance to the rafters. It doesn't attack you, and it drops the deep ring when killed.

Screaming Evangelist (Dorhy) - An evangelist in Irithyll. It screams and it seems to be resting close to a locked gate. It drops Dorhy's gnawing.

Peaceful grub - A peaceful caster grub near the entrance to Rosaria's bedroom that drops red sign soapstone.

Heysel grub - Yellowfinger Haysel that turned into a grub, found in Rosaria's chamber after defeating Abyss Watchers. It drops Heysel's weapon and her crown. It's peaceful.

Pontiff Knight wielding a scythe - A pontiff knight before the Pontiff Sulyvahn fight that wields and Scythe. The scythe also drops if you manage to kill him

Corpse-grub in Irithyll Dungeon - Locked corpse-grub that drops great magic shield.

Tree bitch - A tree witch in the painted world that crawls, and cries before you access it. It also has unused dialogue in game files, and makes a ladder go down if killed.

There are probably more, but i don't remember them.
