Just use a phiomia with a lot of stimberries.

1 Tame a phiomia with bolas and a club

2 Build a structure of your choice to house the phiomia and collect poop

3 Gather tons of stimberries (I use a moschops)

4 level up the phiomias food only. Dont waste points on other stuff your never going to use it for travel.

5 SHOVE THE STIMBERRIES DOWN ITS THROAT AND GIVE IT DIARRHEA LIKE YOU AFTER HAVING TACO BELL

6 You now have a lot of poop. Just dont tell PETA what you did. :)

Toilet glitch doesn't work on asa :'(

Fun fact. At least on mobile, spinos poop 2 large feces at a time

Force feed a phiomia to get a lot of poop, then just put in the dung beetle and you get fertilizer plus a little of oil

Just use the toilet glitch. Build a toilet and supply it with a water source. Use it when your constipation is full (your hunger bar changes color). After you’ve done your business, hop off the toilet, flush and you’ll get a fertilizer. But your constipation won’t go away. Hop back on the toilet and repeat. Unlimited fertilizer.

Tested on PS4.

I just tamed about 8 dung beetles and about 3 phiomias and then lvled food into the piggies and the bettles into weight. I have had these beetles for just 3 irl days and already have almost 1k fertilizer. 10/10 would recommend doing what I did

Force feed phiomia stimberries and see what happens ;)

Get a few dung beetles and put them on wander put poop in their inventory and they will get u fertilizer and oil use bigger poop for better income

This is gross but toilets can make fertilizer if they have a water line then u have fertilizer 😶

MULTIPLE WAYS: Will Need - Stim Berries, a Phiomia, a compost Bin and Thatch or a Dung Beetle. Process - Put Stim Berries into a Phiomia and have it consume them. Take the Poop created by this process and put 3 of these medium sized poops into a Compost Bin with 50 Thatch and wait for it to produce Fertilizer. Dung Beetles will produce Fertilizer by putting Poop in their inventory.
