Pluto's Playmate 1941

Pluto is playing with a ball on the beach. The ball goes into the water and starts moving in strange ways, because a sea lion is playing with it. Pluto does not want to share the ball, and eventually tries to bury it, but the sea lion is too clever. Pluto goes after the sea lion, but has to tangle with a persistent octopus. The sea lion saves Pluto, and resuscitates him, so Pluto agrees to play.
