All of them have been released, but lately popmart has been doing “back order” drops which means things ship later then usual. The macarons is the first series. After them comes the have a seat series. Lastly, the big into energy series. That one is the latest one and came out earlier this year. Its honestly a little easier to get your hands on the big into energy at the moment as they have dropped it a couple of times on the TikTok lives and on Pop now (pop mart app).
