Yup, I think poop is funny. So does DeVito, and the whole cast and crew of It’s Always Sunny in Philly.
The thing is that if you poop you also pee. So you’d also need a container for pee, and a neat little shovel for the poo. And for your doog. Your dog needs water too, you know? Another container for him, and a week or so of potty training for the pet.
I understand that you can make helluva fertilizer from poop. Say, you’ve got some coding skills and you code some horses in for that matter. That’s a load of horseshit for what you want, every day, and besides the meat (for the dog, and you). Then you can construct a Ballista and shower shit on the whole town. So zombies can smell you, your horses AND your dog a thousand feet away. Until you decide to clash your minions, wielding your weapons of poo and pee, with the undead predators.
Or you can have that CBM. The one that’s stuffed in your digestion system, telling it to make better use of the consumptions. And another CBM that melts Zs into shit on sight.
