PopCap Games announced a major update to its smash hit Plants vs. Zombies for the iPhone. The update adds nine new mini-games, all from the original PC/Mac edition, that players can access via Crazy Dave's Store.  The content also includes a new micro-game and Game Center achievements.

Players can unlock three mini-game packs (each containing three new mini-games) by purchasing the packs from Crazy Dave with coins earned during gameplay or by tending the Zen Garden.  Players short of coins, or wanting immediate gratification, can purchase the Sunflower's Golden Chest, Marigold's Coin Pot and/or Stinky's Secret Stash via an in-app 'coin' purchase of US$.99 each to unlock the new content instantly.

The new mini-games packs include fan favorites such as:

Game Pack #3

-Seeing Stars: Unravel the mystery of the star-shaped pattern.
-Bobsled Bonanza: Melt the ice and defeat bobsledders and Zombonis in this frosty battle.
