There is a video of monkeys riding capys and grooming them in u=tube.
This must be their way of sayng “Shut your mouth Mr. We do what we want and go where we please! You better recognize fool!”
That monkey is brave-have you seen the teeth on a capy?
I actually think the monkeys were “grooming” him, looking for bugs, etc.
