March 21, 2015 - The Pokemon Center brings a couple new lines of Pokemon for their Pokemon Petit Series Promotion. This time their series features the Kanto and Johto starters! It looks like they are offering the same merch as they did in the past for the other Pokemon Petit promotions (such as Latias & Latios) with an addition of a Conbi Set that features the RG starters only (which is unfortunate because I would jump all over it if they also had one featuring the Johto starters).
