Bernard

They have grabbers on the tips of their tail, which they use to grab and drag down bodies from high in the mountains, where it's too dangerous for people to spend the extra energy to retrieve extra weight. They grabbed one of those corpses one day, trying to scavenge for food out of desperation, and forgot to let go of them. It walked up to a base and got rewarded with a piece of meat for it, so now they do it all the time.
