Can you really find Shroomish on Route 11 in Black? I've been wandering around in every bush on that road for several minutes now and haven't seen it. Also my pokedex reads area unknown.
Possible theory about origin
Just got my mind blown over on GameFAQs- could Shroomish be at least partially based on a dinosaur egg? I mean, look at it- given its shape, it's not that much of a stretch, and the color scheme is a dead ringer for a Pokémon Egg, right down to the green spots. Considering Breloom's possible dinosaur origins already being documented on that article, I wouldn't say this would be too much of a stretch, just wanted to throw the idea out on the talk page before editing it right into the article, see if anybody agrees with me. - unsigned comment from Missingno.
