A school of fish is out at sea. When the school is attacked by hungry seagulls, one of the fish flees towards the shore. The tide is out and the fish finds itself cut off from the sea in a tidal pool. The inhabitants of the pond eye the intruder curiously and defend their territory in their own way. Suddenly a seagull appears and it becomes dangerous for the animals. With their combined strength, they manage to drive the troublemaker away.
