Key?!

Shi-Shi likes Curious George, and she has DVD, which has 6 episodes in. She asked Pappy to turn on the George DVD, and she said "KEY" when it was time to choose an episode to watch. The episode she wanted to watch was "night zoo", so Pappy was really confused and thought she mispronounced " key" instead of "zoo". However when she asked to turn on the DVD in the afternoon, Mommy noticed that Shi-Shi said "key" because keys were one of the main pionts of the story. The story is like this; George went to a zoo to watch a panda bear and was trapped in a zoo. He found keys, which he thought he could unlock a door and get himself out. Instead of openning a door to lead him out, he opened all the animals' cages, and all the animals were out in a same field. He noticed his mistake and figured out what to do, and that was all about the story. Mommy is not sure if she really follows the story or not, though, she remembers what is in a story at least!
