Use moshop..it more safe than tame satan tickle bird

Use the therinzs tickle attack will running. I get ove 1k in a few seconds

Tame a Moshops if at start of the game and just harvest some bushes. If not, then get a lot of Gigantopithecuses and put them on wondering. Then just wait.

Get moschops it farm's it really good just drop the berries and you get fiber really fast

Therizino is the best at gathering fiber.Mine gathers like 1000 from 7 bushes

On Abberration, ravagers are actually able to gather small amounts of fiber and mushrooms from those blue glowy mushrooms in the biolum region. While you don’t get much fiber, it’s good in the early game if you need a small amount.

Megatherium is easy tame and theri isn't bcz theri also take so long! So tame a Megatherium for fiber!

When going to a swamp, bring a therizino to get an easy 100k fiber in minutes, I did this for about 15-20mins and I made over 859k and a good amount of rare flowers and rare mushrooms
