Thank you, Scarlett. If the American bimbo has an I in the 6th place, though, then so does the overall word. But I've not come across that word; the usual word - and the one given in Chambers - has an L in the 6th place place. I'm still puzzled!
Now I've confused myself even more. It does say twinkie in dictionary....think it's twink because the 'American STARTS taking over', then el backwards gives twinkle then toes.
I agree with Bill. For the same reason, I had arrived at TOES as the last four letters of the answer but the fact that TWINKLETOES is not in Chambers is not a good sign, even though it is a good fit in many ways.
