His crops are not growing properly, so Gumby helps in every way he can and finally divides himself into a lot of Gumbys, which go over the fields with many different farm machines. It turns out that the wild growth of the crops is the result of a gopher who In order to feed his large, hungry family, injects roots of corn plants with a chemical that makes them grow into giant ears and roots.
