I recently started watching the Ruby & Sapphire Anime, and in the episode 'You Can Never Taillow!", Brock makes "sandwiches" and Team Rocket steals them to convince a flock of Taillow to help them capture Pikachu. Anyway, it shows them to you just before they're eaten by the Taillow, and they're not even sandwiches. They look like Onigiri, a Japanese stuffed rice ball (I know this because I once got monthly boxes that would teach me about countries, one of which I got was Japan, and it had a recipe and description of Onigiri.).
Anyway, why do they refer to them as sandwiches if they're rice balls? Is it just because kids won't know what rice balls or Onigiri were? And correct me if I'm wrong, but this sort of thing -- I think -- has happened with a lot of Brock's food.
