They are always a good help when hatching wyvern eggs they tell you when the elecritacil storms near so you can put them in your invintory and defend your base from enemys because all your turrents will be out
They halve the weight of whatever you put on them, and can be carried themselves. Makes them extremely useful for getting a lot of metal on one trip. Be sure to upgrade their carrying weight to allow for more!
Fun fact.. Bola does work. My friend was lagging kinda bad, so i used a bola as a joke, but it actually got restrained. Good for if you need to run to get food for the tame.(only lasts a little while and seemingly everything wnjoys a free meal, so carry berries and seeds on you)
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.
