Use the Yak Lasso on Wild Townlong Yaks, then fight against them to see if they are suitable for Bluesaddle.
I can't find a single good yak here. ALL the yaks are bad!
Some are too stinky, some too fight-y, others just scared.
You look like a lucky <race>. Here, take a lasso. See if you can find a good yak for me.
