"Where is my mother?!?"
"Mr. Frog, do you know where my mother is?"
"I don't know where your mother is, but maybe the raven does."
So the little mouse goes off to find the raven.
"Mr. Raven, do you know where my mother is?"
"I don't know where your mother is... but maybe the cat knows..."
So the little mouse goes off to find the cat.
"Mr. Cat, do you know where my mother is?"
"Maybe she's in my mouth!"
So the little mouse goes to look inside the cat's mouth.
"Hi, Mom! What are you doing here?!?"
