Find a jerboa. Strike it with basically anything you can get your hands on and it'll go to sleep. Tame it and enjoy! The weather patterns are:
Looking up and hurming- sandstorm
Growling with tail extended- lightning
Growling with digging- heatwave
Sniffing air with odd eurble noise- rain. The last one is my favorite, as it fills all your reservoirs. You don't have any? Make em quick!
The first thing I saw on valgero was this floof ball. And I'm yelling and crying at wildcard bc I don't want to punch it to tame is so cuteee. So I put it in a thatch trap and a looOoooong time later in the game I came back with a ptera to see it still in the trap. I carry with it still being wild. To this day I have never punched a jerboa. Only keeping them in safe little houses.
