You can now specify a mount that you have hitched to rest or stand:

A yellow kank falls in behind you.

> rest kank
You pull on the yellow kank's reins.
A yellow kank curls up on the ground.

> stand kank
You pull on the yellow kank's reins.
A yellow kank rises from the ground, and clambers to its feet.
