Therizi is thé best-seller for farm fiber
Highly suggest moschops as they are easy early game tamed unless they ask for a freaking wyvern egg or something
Use moshop..it more safe than tame satan tickle bird
When you put your Moschops on wander they gather more fiber than you'll ever need.
I forgot about mine and when I found him he gathered over 5000 fiber!
Mantis with 2 sickles are really good at getting fibre
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.
Use a dire bear and attack while running, you will get a lot of fiber in no time.
Therizino is the best at gathering fiber.Mine gathers like 1000 from 7 bushes
Get moschops it farm's it really good just drop the berries and you get fiber really fast
