I must smell "tumduddy".

[highlighter]

My father's Dragon Chapter 4 " He lay very still and the mouse, for it was a mouse, hurried away muttering to itself, “I must smell tumduddy. I mean, I must tell somebody."
I don't understand 'tumduddy'. I can't find this word in any dictionaries. I really need your help. Look forward to your answer.

"Tumduddy" does not exist. He was mixing up the sounds of "tell somebody" and saying "smell tumduddy".
