Yotsuba is bathing with her mommy when Yotsuba notices her mom' pubic hair is gone. She asks, "Mommy, what happened to all your hair down there?" Her mommy doesn't want to explain this to her, so she simply responds, "I lost my sponge." Yotsuba says, "Don't worry, Mommy! I'll help you find your sponge!" Her mom just chuckles and lets it go at that. A week later, Yotsuba comes running up to her mommy and says, "Mommy, Mommy! I finally found your sponge!" Her mom asks, "Oh, really? Where did you find it?" Yotsuba answers, "The woman next door is washing Daddy's face with it!"
