When one of my daughters was 3 someone handed an iphone with one of those apps with an animal that repeats things back. She said something with the word "color" in it, but it came out "cala."

It repeated it back (incorrectly) and then she got stuck in a loop of saying "not cala, cala!" and it repeating it back, getting more frustrated each time.

I'm guessing that was Talking Tom (the cat). My 2 year old daughter has gotten into similar loops with it several times. Usually though, it's just along the lines of, "No, YOU!"
