Flip is a lazy frog who just wants to lounge around in his hammock. But being the great inventor he is, he has it rigged up so that another animal below is running on a treadmill which gently rocks the hammock. When his old-lady employer catches an eyeful of Flip is up to, instead of mowing the lawn as he is supposed to be doing, she gives him the business. Flip is not happy. One thing leads to another and he winds up inventing a robot, a machine that will cut the grass for him. That's where the bulk of the cartoon and the laughs begin. The robot is a real hoot, human-like more than anything else. The ensuing battles between Flip and this robot are very good with clever sight gags involving what the robot mows. Good stuff, with another totally-wacky ending that you'd see in an early '30s cartoon.
