Main offense: Completely uninspired
What went wrong: Someone just slapped a smiley face on a sunflower and called it a day.
Lesson learned: The best Pokemon are those that have creative designs that don't immediately remind us of things from the real world. Pokemon like Pikachu and Spiritomb are so cool because they're completely different from anything we've ever seen before. Even Pokemon like Octillery and Typhlosion are still cool because they've added a creative element to the animals they were orginally inspired by. Sunflora, on the other hand, is just a flower with a face on it, and barely qualifies as a Pokemon in our opinion.
