Any information on these Tamagotchi P pierces?

I ordered this tamagotchi off eBay today. It comes with two pierces I've never seen before. One like a cake and the other baby themed. Has anyone got them? And what are they like?

*P's. The tamagotchi is actually called P's, not P.

Anyway, the second is the baby change pierce, it changes some of the characters into their kiddy form (except spaceytchi, he changes into a grandpa for some reason?), also few backgrounds and probably a game.

The first I am pretty sure has something to do with berries... There is a thread about them, but I can't really find it right now. I know that the first one gives you several additional characters, though.

The first pierce is called Berry Sweets and the second one is Baby Change.

Berry Sweets has a game on it while Baby Change does not. Change Pierces so far released hasn't had games. Both pierces do come with a buyable wallpaper (or two, depending on the Pierce), some food items, a toy, accessories and/or clothes, a destination, an icon background, and of course new characters.

The characters on the Berry Sweets Pierce has three raisable characters. You can use items provided by the Pierce to evolve them. The Baby Change Pierce allows in-built characters (such as Kuchipatchi) to transform into different versions of themselves.

Here are some useful images for you:
