Chapter 28
While in the fields the two have some parody type thing as Howard slowly advances in the farming training. First he farms with a hoe, with various moves, and is then upgraded to a handheld machine when he wants to learn something harder. The next step after that is a cow itself and Howard begins to shy away from it but Grandpa attempts to convince him.
Her Grandpa brings over some of their best fertilizer and Howard takes it in both hands to smell. He doesn't know what it is. He comments that it smells good and of fresh grass and when hearing that it's because the cow ate fresh grass, he finally understands what it is he just touched and smelled.
