Jerboas are very easily knocked out. It takes about three to four punches, or one boomerang. Once knocked out, they only have 30 torpor and wake up very fast, so I suggest gathering everything you need beforehand. If you are having trouble getting the berries needed, make a whip, they are excellent for gathering fiber and berries.
Basically if you want to tame this on Ark Mobile. I know that you can find this guys in Dungeons. Just kill it grab the implant, complete the dungeon us the revive pad. Use your Amber and revive it knock out it and tame it and Boom you have one of this guys.
