Jolt never asked for much, as far as the zebras were concerned. They did not know the true price of their golden accessories. Just think of it - the pony will give whole village light and warmth for just a few hoops of the yellow metal!
He even says he’ll come back later with even more miracles… How could you say no to that?
Zecora looks absolutely adorable here, and seems happy to meet new people :D
Edited
Unlike ponies who get theirs magically,zebras go through a ritual to get theirs tattooed.
The tattoos happen to be magical as well/headcanon.
HISTORY!! It can be kinda fucked up like that.
