First, tame a mantis, then take a really good sickle and equip it to the mantis, then play a walking game until your fingers hurt, then you should have as much as you need.
gigantopithecus > theri
This guy collects SO much fiber. You can't get it while riding it, but just dismount it on top of a couple of bushes. it gets 50-70 fiber per bush. I just tamed one and now I have 1374 fiber
Dire bear is the best for fiber, he doesn’t get the most per bush, but he can get through ten bushes in the time a tickle chicken or moschops could make it through one
Use moshop..it more safe than tame satan tickle bird
Step 1.Tame a tickle chicken. Step 2.Tickle all of the bushes you can find. Step 3. Make an army of tickle chickens and repeat Step 2. Step 4.Find a use for all of that fiber
Use the therinzs tickle attack will running. I get ove 1k in a few seconds
Tame a mantis and equip it with Sickles
Therizino gathers so much faster than anything in mobile
1) Moschops cannot be ridden in mobile so you're stuck with wander mode = you just list you moschops for 2 weeks or forever
2) You "tickle" multiple bushes at once for rapid gather. With the correct circuit, they have respawned when you loop around, so you can go till you fill up
3) You're riding a death machine instead of on the ground holding a totally useless weapon when raptors and terror birds come a knocking.
Scythe. You literally just need a scythe and then go running through the bushes on the shore and you’ll have thousands
A moschops can be tamed with like 1 berry and then get you 1000s of fiber per click (yes, over 1000 per click if you are in the right area) -c0mplekz
