It wouldn't be a farfetched idea, as real fruits also come in different shapes and colors. And Rawst, Pinap and Nanab variants already exist in LGPE and GO (although they're all just recolored in silver and gold to show the effect gets stronger).

Now, how comes a newly hatched Tropius already bears fruits in-game? On another note, was Tropius ever officially shown with different fruits?
