Is Perry related to Polly?

I'm not sure what leads Amara to say some of the things she says. You know when you ask a child, "What does this animal say?" and you list all sorts of animals? Well, some animals don't really make sounds, so I make them up. For instance, a bunny says, "Hippity Hop," a giraffe says, "Stretch!" and a hippo says, "Hip, hip, hip, hippopotamus, Hip hip hooray, God made all of us." You get the point.

Anyway... so I've always told Amara that a parrot says, "Polly wanna cracker?"

We're leaving the pizza place today after lunch and she starts saying, "Perry wanna cracker!?" Apparently Perry is Polly's brother....
