Yes exactly, though feathered dairy producer might be rare, because I do bias towards the IRL direction. XD
Also “Wooly Mount” = Llama? I wonder why MC Llamas dont give Wool because that would totally be possible, probably to not make Sheep useless.
And yeah “Der Eier legende gefederte Woll-milch-wolpertinger” will be present on all Islands if the World is Easy, or at least present on the first Island. XD
Edit: Also if you are small enough even a Rat is ridable. XD
