To Tame A Thunderspine

Everyone is curious about Lizi, but the truth is, she sticks out like a sore hoof. Lizi herself is starting to wander more and more, as if she's looking for something. She mostly rests by the water on the mud. I'm sure it's fine, but I know thunderspines like to make a bedding from grasses. I've got an idea better than grasses. Will you help me gather wool from the plains? I'll weave her a blanket and some toys.
