Sure, I would want some. I like berries irl, and the ones in the pokemon world look big, pretty and juicy, if a little whimsical. I think they would taste amazing. I would look for a berry with a sweet flavor though, because that's the way I like my fruit to taste.
I would most want a roseli berry, the art looks like a strawberry, my all-time favorite fruit. I want a watmel berry too. The design and name both scream watermelon, and they can be really refreshing in summer. I hear that Japan's Densuke watermelons are some of the best in the world, so maybe the watmel berries taste like that! I will add a payapa berry to my basket next. Seems to be an anagram of papaya, the color is more passion fruit-like, but if it tastes like either that's a win. Let's top it all of with a pecha berry, my pink, heart-shaped peach.
