Brock and Ash from the Pokémon anime are two best friends who travel together across many regions, catching Pokémon and exploring the region however this region seems to be made for men to eat more than they are used to since all the food and ingredients are incredibly tasty, not only humans but also Pokémon seem to be on the larger side and Brock and Ash are catching up as expected during their adventures. The further they travel the more delicious food gets which has made them balloon up.
