Plummy tries his hand as a farmer: he turns into an agricultural machine and ploughs the soil and sows the seed corn. As a „sun" he helps the seed growing and ripening. Plif and Plops turn into crows and pick up the seeds. When Plummy discovers the two greedy crows he tries to scare them off - without success. Only when he morphs himself into an ugly scarecrow, it gives them such a shock that they can't help turning into plonsters again. Plummy tells them off and gets them to harvest the grain. Then they turn into a threshing machine, a mill and into an oven - and very soon three delicious pretzels are ready to eat. The moment they start munching, a little bird shows up and starts picking up the seed. Plif, Plops and Plummy turn into funny scarecrows. The little bird flies off and the three Plonsters are all having a big laugh.
