That's nothing -they revoiced the Teletubbies and Bob the Builder! The Tellytubbies! Eh Oh? I'm sure it would really confuse American kids hearing "eh oh" in a Brit accent
Bob's hedgehog friends turn into porcupines and his cheese sandwiches become PB&J. it's not like American children don't come across cheese sandwiches, and hedgehogs feature in lots of kids' books. My American friends with sprogs don't understand why these were changed, either.
