Well, most of the time, at least. In this clip, a restaurant employee tries to steer Sammy back into the harbor with a chair.
That's not going to work.
So the man does what he's likely had to do for ages to get Sammy to go back home. He throws a fish from the restaurant back into the harbor.
And Sammy, with a mighty plunk - Sammy is a portly seal - is gone.
But a moment later, his head pokes back out from the water's edge.
An unimpressed dog barks in his face.
