Ferrero Kinder Surprise Italy 'The Flintstones' (2000) Set 1 - Pt 1

So here's the deal: I've got a bunch of these Ferrero (Italy) Kinder Surprise/Surprise egg Flintstones figures but can only identify six of them to a particular set. The insert below shows six figures along with several additional pieces and I'm speculating that the designation "K01' means 'Set 1' or perhaps 'Series 1'.

For size, I'm going with 60mm
