It's widely known that Snivy is the coolest starter in Pokemon Black and White, and as of today the Grass Snake Pokemon has yet another reason to look smug. You can now unlock a special Snivy in Pokemon Rumble Blast with Grass Boost, a powerful ability that increases the strength of Grass-type moves and raises defense against Grass-type attacks. So if you like punching toy Pokemon and want to be able to hit them even harder (especially the Fire types!), read on to find out how to get your very own extra awesome Snivy.
First, go talk to Munna in Easterly Town in the west corner south of the release point. Then enter the password 08357338 to unlock your Snivy. Enjoy!
