@beardalaxy funny story I have about Bellossom and why it always has a soft spot in my memory. When I was younger and playing Crystal version, I thought Vileplume evolved into Bellossom and kept wondering why my near level 90 Vileplume wasn't a Bellossom yet.
When I got my DS with Pokemon Diamond, I bought the Pokedex book and ONLY THEN I found out that it's Gloom that needs to be evolved with a Sun Stone. So I finally got my Bellossom.
