Can someone please explain to me the differences (if any!) between all these Iggle Piggles?!

[Pesha]

I have seen Dancing Iggle Piggle, Blanket time Iggle Piggle and Talking Iggle Piggle and the only real difference I can see is the price!

DS2 would love Iggle Piggle for christmas but I'm getting so confused over which one to get, especially as I'm looking online only so can't actually get a hold of them and play with them have a proper look at them.

Please help me!!!

Dancing Iggle Piggle dances
Blanket time Iggle Piggle - Im not sure?
Talking Iggle Piggle talks and sings
Sure either would be fine, they are very expensive tho for what they are! Got my DD Iggle Piggle and Upsy Daisy 6inch soft toy things and I do the singing/dancing myself
