Walruses and Seals

Flower is taking after me in the 'talking in her sleep' department.
She's at home napping in bed next to KG.
KG just sent me a text with the following:
"River started to fuss so I got up to get her. Flower says, "I'm tired" and rolls over.
I made River a bottle and got back in bed to feed her. Flower rolled over again and with her eyes still closed says, "walruses and seals swim in ice water"
What?! So random. We have no idea where she got that but I laughed so hard when I got the text. It was nice comic relief during work.
