Ain't Nature Grand! is a 1931 Looney Tunes short starring Bosko. The cartoon is now in the public domain as Sunset Productions, the owner at the time, failed to renew the copyright in time.
Bosko goes fishing next to a sign that says no fishing. He starts to feel sorry for the worm that he has brought; instead he uses the letters on the sign to act as worms. He catches a fish, declares that it's cute and attempts to keep it as a pet. The fish proceeds to spit at him, before jumping back into the water. Meanwhile, the worm is not safe yet. A bird chases him; but he runs into a hole. Meanwhile Bosko finds two ladybugs dancing on stones next to a waterfall as a spider is playing his web as a harp. A pelican rises up from the water to throw four frogs right next to Bosko. Bosko and the frogs sing and dance. The two ladybugs are troublesome; they use a wasp like an airplane, a flower as a propeller, and a beehive and tree branch as a machine gun. They shoot Bosko with several bees, driving him away and making him fall into a water fountain. But Bosko, who looks happy, pulls out his hat and tells the audience that everything's going to be alright.
