While exploring the concept of vegetarians / nature-lovers, I have come across some great mods that I wanted to gather together to showcase to others.

* Characters
Charlie, the Gardener
Wanda, Nature's Frenemy
Walter, the Botanist
Winnie, the Shepherdess
Wynn, the Environmentalist

Charlie is great at summoning butterflies / flowers, and causing rain / making things grow, and making backpacks. Wanda can turn rot into manure if beefalo or pigs are hard to find, has an accelerated agriculture knowledge tree for early Improved Farms, and she benefits from flowers like Charlie. Walter starts off with manure, has some basic agriculture knowledge, and can fertilise farms during Winter. When Winnie is enabled - even if no one selects her - then ewelos spawn (look like ewecus but behave mostly like beefalos, except have a mucus attack), which she can shepherd to base. Wynn gains sanity for planting things and is able to recycle tools.

* Game Tweaks
Beefalo Milk and Cheese
Break the Ice
Butterfly Effigy
Fish Farm
Fruity Weapons
Infinite Pumpkin Lantern
Mushrooms
Rot Machine

The dairy, fish and mushrooms are great for vegan / vegetarian characters. Rot machine complements Wanda since she can put anything into it to make it rot quicker, which she can then turn into manure. Fruity weapons and infinite pumpkin lanterns are just a bit of fun, but can have a good use
