[TOMT] [Animated movie] character says “no” to a guy a few times then says “let me think..no”

It would be a kids animated movie, but that’s all I can think of. Some guy says something and someone responds “no”, the does it again, “no”, does it a few more times. The final time the character goes “let me think…no!”. All I can picture is the character being a mundane or not excitable character, but it’s paining me I can’t remember it!
