At a park with a little stream:
"Shall I go into the raging waters?"
On the way to a friend's house:
"I'm running as fast as my little legs will carry me!"
At the friend's house, upon being asked if she would like to see something cool:
"Will it turn me into a princess?"
While wearing her kitty jammies:
"I'm the big girl kitten and you're the mamma kitten."
While wearing her new flower pot jammies:
"I'm the flower and you're the pot because I'm growing in you."
