Cash - "I would have blow power! I can blow so hard all the things and bad guys fly away and go like this..." He enacts being tossed around be wind.
Legend - "I have fire power! I have fires that shoot out my hands and fire on the bad guys. And I am super strong and fast. I am a brave SUPER FIRE HERO LEGEND!" He begins shooting fire at invisible bad guys.
Kayla - "I have heart-shape-o. I change bad guys' heart into good guy hearts." Smiles coyly.
Me - "I am super-mom. I have duplication powers so I can make lots and lots of me's. One mommy can feed Penny while one mommy plays with you guys, while one mommy fights bad guys." Sounds handy to me.
Cash - "What is Penny's power?"
Legend - "Penny has the power of EATING!"
Cash - "Yeah! She eats ALL the FOOD and gets enormous!"
Legend - "Just like the Hulk can grow. Penny grows and grows huge and huger and squishes all the bad guys with her huge baby feet and cute huge bum!" The boys and Penny are now all yelling at each other.
Cash - "Yeah! And she can eat more food and more food and get huger and huger and EAT the bad guys!"
Cash and Legend dissolve into masculine grunts and skinny little flexed muscles.
Kayla, calmly - "Penny's just such a cute baby. Right, Auntie Kate?"
Me - "Right, Kayla."
