TAF babies -- what was Hasbro thinking?

[Skeen]

If you look at most series of ponies that were just 4 or 6 to a set, then all 3 "species" are represented- earthling, pegasus, and unicorn.   I think in this case, that 3 way split just happened to be even.  It also means they didn't need to have multiple poses like if 4 of them were earthlings.  I would guess 6 babies were chosen based on the fact that they are all different colors for variety and then somebody just slotted them into species!   So, perhaps a bit of all three choices!

I am with this theory. They were aiming for two of everything and for some reason this was the combo they went with. Oh Hasbro you puzzle us so

Agreed.  The only other large mail order set of babies followed the same pattern of 2 of each species.  They probably just went with that idea to appeal to kids who loved each species best - that way, no matter what species they loved, there would be 2 ponies for them to coerce their parents into buying.
