Ugh I wondered if this event would be hard for newer players or ones without wool producers. If you have $40000 gold you can buy a black alpaca. I didn't have enough coin for one for a while. But I'm half way done with the fifth bubble on the quest and I've used up maybe 60? wool already from what I had stored.
Greasyfork1's suggestion is an option. You can get a sheep from one of the adventures. But so far At level 33 I haven't gotten anything but decorations, and each adventure takes one day to do. But do watch the daily videos you can get coin or items each day doing that. I got a dragon my first week from one.
I don't know how easy the event will be if you just buy the sheep with gems.
Edit.....ha, people posted before I finished typing. Stables are a fabulous idea gridgirl.
And thank you Stormaraura42 for the info on the bunny.
