I have about 10 double chests of rotten flesh (my zombie pigman farm is working nicely thank you very much).
While rotten flesh is great for dogs, I just can't imagine using any more than a hand full of stacks for them.
I have also been using it for some decay timers. But that uses 1 every 5 minutes. So, in about a third of a year I'll have used it up….
Does Rotten Flesh have any other uses?
Best Answer
Rotten flesh is quite useless but it can be used as a good source of food. Despite having a 80% chance to drain your hunger, it heals 20% of your hunger. You can cure the hunger by drinking a bucket of milk, which may seem like inventory space waste, but still...
It does heal wolfs however without hungering them.
I honestly don't know what else you can do with it :/
As for the spider eyes and glass bottles, I recommend you start your own brewery (not beer, just potions). With the spider eyes, you can create a mundane potion or a potion of poison, or you could ferment the spiders eyes using mushrooms and sugar and create potion of invisibility, potion of weakness, potion of slowness or potion of harming.
For more information, I recommend looking at the relevant wikis:
