They are only able to be found in dungeons on the island mobile . Like so people see

So in my dads computer, I was playing ark with my neighbour and tamed a jerboa on the mountain she built her base next to. I call it the safe mountain seeing as there’s no agressive Dino’s (allos,t Rex etc.) once I got back to my base, I had it on my shoulder and tried throwing it to my featherlight, it wouldn’t appear, moments later after going outside, my jerboa appeared out of nowhere! Its name is invisibility now ;-;

Probably the cutest thing you have ever seen

On PS4 they only seem to spawn at level one so that early game players have a food source. Tame them for helpful weather updates and cuteness.
