In their continued promotion of Pokémon HeartGold and Pokémon SoulSilver, Nintendo has decided to release a new commercial starring Dylan and Cole Sprouse, best known as Zack and Cody from 'The Suite Life on Deck'. Below is the official press release.

The only way to make a day at the beach better is to play some Pokémon. Longtime Nintendo fans Dylan and Cole Sprouse of Disney Channel’s The Suite Life on Deck did just that when they filmed a new commercial for the Pokémon™ HeartGold Version and Pokémon SoulSilver Version games for the Nintendo DS™ family of systems. The commercial will begin airing on Aug. 16 on Cartoon Network, Disney XD, Nickelodeon and Nicktoons.

“I think I like Pokémon HeartGold and Pokémon SoulSilver because we played the original Pokémon Gold and Pokémon Silver, so to play these games again is really nostalgic”

In this behind-the-scenes video, fans can get a look at Dylan and Cole’s day on the beach in Santa Monica, Calif., as they play the games, battle against each other and race to see who can rack up the most steps using the Pokéwalker™ accessory, a small pedometer-like device that lets players bring their favorite Pokémon with them wherever they go. By walking, players earn Watts, which are used within the Pokéwalker to encounter and catch wild Pokémon or search for hidden items that can then be transferred into the Pokémon HeartGold Version and Pokémon SoulSilver Version games.

Both Sprouse brothers have been big fans of the Pokémon series for years. “I think I like Pokémon HeartGold and Pokémon SoulSilver because we played the original Pokémon Gold and Pokémon Silver, so to play these games again is really nostalgic,” said Cole Sprouse.

Pokémon HeartGold Version and Pokémon SoulSilver Version offer detailed graphics, intuitive touch-screen features and hundreds of Pokémon that players can catch, battle and trade. Players can also interact with their favorite Pokémon by choosing one to follow behind them as they explore the Johto region. These combined features offer a rich game-play experience for longtime fans and newcomers alike.
