Look here the crown store showcase (
https://www.elderscrollsonline.com/en-us/news/post/58315 ):
We get a mournhold packrat as inventory pet, it grants 5 additional inventory slots (aviable: June 11 at 10am EDT on all plattforms), what do you think? (i think it is cute, but another crown store pet?) Do they know how much crowns are spend on the (way to expensive) crates? I wish it would be aviable ingame...or at least they make some more pets ingame aviable... maybe through fishing, gathering, hunting (all random drops)... well i guess we should be happy that the new antiquity system comes with one more ingame mount ( still wonder why they made just one, well maybe they release more in that style). Anyway just wanted to inform you.
