In the video, Zoey watches the Super Bowl while grounded, this proves how Zoey Balkin's voice is Ivy.
Zoey's dad: Zoey, how dare you get expelled for singing "Let Me Play With Your Poodle" in class! That's it! We're going to the hospital to get your voice changed!
Zoey: No no no no no no no no no no no no no! Please dad, I'm sorry!
Zoey's dad: Too bad!
Dora: No Dad! Please don't let them change my voice! All I want to do is annoy Boots by singing "D-D-Dora" to him repeatedly.
Dora's dad: Too bad Dora! This is what you get for interrupting class by singing "D-D-Dora" repeatedly! Then, you did the same thing in detention! When we go home, you will sleep until your show is cancelled!
Doctor: The doctor is here.
Zoey's dad: Can you change Zoey's voice because she sang "Let Me Play With Your Poodle" in class?
Zoey (speaking in Ivy's voice): Oh no! My voice is Ivy! Now I sound like a cute 4-year old girl!
Doctor: How's this?
Zoey's dad: Much better! Let's go home now!
