They were always there, just changed the tube from circular to hexagonal, getting rid of the letters lids in the process.

They also had to take out the blue ones, as until recently, there was no way to colour them blue without using artificial ingredients, and they're just trying to make candy less unhealthy.

Personally, I miss the light green ones being white chocolate which they did for a limited time; I have to make do with the orangey orange ones.
