Pepperoni By The Pool

Grand-daughter #1 came up to me yesterday and told me that she wanted to go swimming (because it's a penguin thing to do).

GD1:  Papa, let's go swimming.
ME:  Do you have anything to wear?
GD1:  Yeah, I brought my "baking soup".

At this point I lost track.  Swimming or cooking.  Did part of that conversation take place while I wasn't paying attention?
She likes to cook with me so I thought maybe I had misheard the first part of the conversation so I prod her to make sure she wasn't talking about cooking.

ME:  What would you like to make?
GD1:  Waves!

I was still a little confused so I put on my "baking soup" and ordered a pizza.

Don't judge me,
