Possibly the most useful creature to go caving with as his small size but large health and damage allows him to withstand onycs,spiders and scorpions haven't encountered a arthurplura yet so not sure how effective he is against it
It literally only took me an hour to tame a level 145 with only 50 mejoberries.
1. Gather berries and put the berries in your last slot
2. Kneel down and walk up to one of them and feed it the berries
3. Now you just follow it around while kneeling down and feeding it berries whenever it's hungry
4. Congratulations you tamed one.
Since they're commonly found in the red wood forest, I recommend only taming one if you're close to water as if you get attacked by something you can jump into the water to get away. Then when you think it's safe just go find your monkey and go back to following/feeding it.
On Xbox, left tab throws you (It's like a spear, the longer you hold down the harder it throws, but there is a max), the other special attack, what you would use for crouching, is what you use to pick up only fiber, and regular attack only picks up berries. It can sprint, swim fast, and jump. Best of all it can wear hats. I equipped my hat with a cowboy hat skin, and it looks hilarious.
These things are great fr caves especially on mobile even a low level can do some serious Damage. I was buy the river once getting fish meet fr my barionic next thing I know it says level 14 gigantopithcus killed level 50 spino. Then I did the chitin cave with my level 120 bred giganto and just killed everything in the cave in seconds. Morale of the story get a gigantopithicus as soon as possible since there easy to tame and are great fr early game as they don’t need a saddle
