The storyboard for the T.V commercial is that there is a woman and she at the store buying diapers for her soon to be baby.

 

She reaches the diaper section and can't choose which one. She grabs various diaper brands and when she picks up Huggies Pure and Natural she goes on an adventure with Totoro.

 

she likes what she has just experienced and decides to buy the diapers.

 

The commercial has no dialogue. It is mainly music and shots of the mom.
