For those following our feed you'll see we just reported that the second assortment of Kre-O Microchangers (confusingly officially known as wave 1) has just been released in Singapore. These are blind-bagged so you'll need a bit of luck getting them all. Or you can use this handy identification guide provided to us by Griffin-of-oz and 0JazzMeister0.
On the back of each blind-bagged Kreon there is a red bar at the top of the packaging (12 to collect in the top-left, "2 in 1" graphic at top-right). Printed in the top right, between the peg-hole and "2 in 1" graphic is a number. That number matches up to the Kreon in the bag - check out the list below to see which one is which:
22981 40 - Singe (Turbomaster Scorch)
22981 41 - Inferno
22981 42 - Autobot Springer
22981 43 - Warpath
22981 44 - Quickslinger (Slingshot)
22981 45 - Rampage
22981 46 - Insecticon
22981 47 - Blast Off
22981 48 - Decepticon Hook
22981 49 - Dirge
22981 50 - Airachnid
22981 51 - Decepticon Bludgeon
Like the first assortment, it is the last two numbers that are the important part. By using this, you can identify all the Kreons in the assortment and add them all to your collection without acquiring too many doubles.
