Ooh, good eye Alchemist Cookie. The new hidden combis are in the game (geesh, that Coin bonus with Mint Choco Cookie + Paprika Punching Bag) but I'm surprised we didn't get an ingame notification about it.

Also, anonymous, I'm going to assume that by "blue blast pet" you mean Foxy Bead. Knight Cookie never had a hidden combi with the Foxy Bead, even before the update.
