I think 'cartoon grandpa as old as dirt' suggests that this grandpa in the cartoon is super old. Maybe he has old-fashioned ideas or looks really worn out. It's a way to emphasize his age in a sort of extreme way.
Well, 'as old as dirt' is an exaggeration to say someone or something is really ancient. So when it's about a cartoon grandpa, it probably means he's depicted as being incredibly old and maybe having a lot of history or wisdom.

I don't quite understand what you mean by 'Grandpa is old'. From the perspective of age, according to the classification standards of the World Health Organization, those over 60 years old could be identified as the elderly group, and grandfathers generally belonged to the elderly group. If it was from other aspects, such as the role of the grandfather in the family or the image of the grandfather in the traditional concept, more information could be added to make it more accurate.
It could be an adventure cartoon where the old grandpa is the experienced guide leading the characters through exciting challenges. Or it might be a comedy cartoon with the grandpa getting into funny situations.

Maybe he got hurt and needed help. It could be a dramatic moment.
Old people might face many situations in their later years. In terms of health, if his grandfather was seriously ill and there was no hope of recovery, the pain of the illness might cause him a lot of pain. Financial and daily disputes, family abuse might also affect his quality of life and psychological state. However, he hoped that his grandfather would not encounter such a situation. If his grandfather's life was lonely, he might feel empty mentally. In this case, the company of his family was very important. For example, he could often go home to visit and chat with his grandfather to make him feel warm. If Grandpa considered going to a nursing home, the current pension market was more complicated. There were different situations in nursing homes. Public nursing homes might not be accessible, high-end nursing homes might be expensive, and middle-grade nursing homes might not provide good service. Moreover, the elderly in the nursing home might not be able to fully express their true thoughts due to factors such as nurses. At the same time, Grandpa should also pay attention to avoid some situations that are easy to happen after retirement, such as blind obedience in second-hand life, accepting all kinds of information, being influenced by other people's emotions, and not living an idle and decadent life.
