Think of a living thing that would be impossible (or at least REALLY hard to train)
Think of natural or usual behaviors of that living thing that you could PRETEND you trained them to do. For example, slugs will naturally stop and pull in their tentacles when approached as a defense against predators. So putting my hand in front of a slug will make them stop on their own-- I can add the command "STAY" to PRETEND that I trained it to do so.
Be creative. The more you relate your "training" to natural behaviors of the living thing, the better your ideas will be.
