Abigail Should Require a Sacrifice

Since the Wendy Rework, Abigail can be summoned immediately, without any cost, at any time, even if it's immediately after her getting defeated. 
As a Wendy main, this doesn't make any sense. 
The original setup was that you had to manually place the flower on the ground after an incubation period where you had to wait for it to bloom. Once it was ready and on the ground, a living entity needed to die nearby. It also would cost 50 sanity. 

I would prefer if these concepts where combined.
My revised interpretation is as follows:

Abigail can still be summoned at any time, but only if a sacrifice is given first. 
A sacrifice must be an innocent creature, Murdered in the inventory. Birds, Rabbits, and Moleworms. 
They must be live, and contained within the inventory with the flower on the ground, then right-clicked to be Murdered. 
In this way, Wendy is very specifically killing the innocent animal and spilling its blood unto the flower to ritually summon-forth Abigail's spirit. 
No, accidental deaths do not count, and having some random weak creature die nearby doesn't count.
It must be a deliberate, premeditated murder of an innocent creature given to the flower. 

Once the sacrifice is given, Abigail can be summoned and unsummoned at will just like right now. 
If she ever is defeated, had her health reduced to Zero, you must then perform the sacrifice again to be allowed to resummon her. 

The ritual sacrifice would not cost sanity because the very specific nature of the process is, itself, the cost.
It cannot be done on accident, you must plan ahead for it. 

In addition to this change, I want Abigail to once again perform the animation where she looks sad when her health is low. 
Yes, adding an Abigail health-bar removes the need for such an animation, but it still is a flavorful addition that adds more expressiveness to the character and can be used to tell OTHER players who are not Wendy that Abigail is getting weak. 
In the end, removing the animation was actually a WASTE of effort and time, because it was fine as it was and didn't need to be removed.
