Pokemon Did You Knows?

[zinja]

I have a few.

1.[spoiler]In Pokémon Stadium, when the player uploads a Pikachu from Yellow, it will be voiced by Ikue Ohtani and have unique sound effects.

Don't really know about that one.... can't find anything online. [/spoiler]

2. [spoiler] If a Pikachu uses Surf in Pokémon Stadium (Japanese), Pokémon Stadium (English), Pokémon Stadium 2, Pokémon Colosseum, Pokémon XD: Gale of Darkness, and Pokémon Battle Revolution it will have a unique attack animation wielding a pink surfboard. All of these games have certain requirements to get Surfing Pikachu or at least get a player's Pikachu to learn Surf (with the exception of Colosseum and XD)

3. [spoiler]

Diamond Dust

This one's pretty cool. Diamond dust is a special variation of snow that appears in Snowpoint City, at Mt. Silver's summit, and in Icirrus City on certain days. It has no effect in battle.


Director Junichi Masuda announced January 10, 2008 on his blog that fans should play Pokémon Diamond and Pearl on January 12, his birthday, for a surprise. The surprise was revealed that Snowpoint City has sparkling diamond dust instead of the normal snow that floats down. It is purely aesthetic, since it only occurs within the city where no battles are possible.
