Exact operations list agreed on so far:
Installing the siren throat in our throat, bag of holding in/as stomach, gazelle leg muscles in our legs, gecko skin on hands and feet, eye stalks in a strategic pattern, and creeping eye in whatever way lets us live of evil. Which I assumed was implicit from my above shopping list.
Things still uncertain:
*Exactly how the creeping eye is best installed. Possibilities include spreading it's living organs amount ours integrating it fully, just sewing it to the side of the bag of holding and connecting it with blood vessels and whatever else is needed to transfer the energy, or having it free-roam in the bag as a pet.
* how many soul energy bottles and soul jars should be bought.
Additional possible additions not yet agreed on:
*If we should get greater biting strength. I vote no, but is we do do that badger or wolverine might be a good source for the muscles.
*A mechanism inside the bag of holding to hold the soul energy bottles, with a dead man's switch that will douse us in case we get knocked out.
*Unless normal food doesn't give us energy, it might be useful to install a large digestive tract, or even several, inside the bag of holding.
- There's likely to be very cheap digestive tracts of cows or the like as slaughterhouse wast that'd let us live of grass or such in emergencies.
- Giant pig stomach should let us eat anything a human can and a whole bunch of other things as well, in very large quantities and process it rapidly.
- There is likely to be some magical creature around embodying the Extreme Omnivore trope. We may summarily invent the Dire Goat, the size of a large horse and able to live of anything from bone to wood to or crude oil.
