This is the reason why Memy9909 is voiced by Julie.
Memy9909's mom: Memy9909, how dare you get expelled from class! That's it! You are grounded for 12 days and as for your punishment, we will take you to the hospital for a voice surgery!
Memy9909: Please no!
Jeff Fatt: Please Greg, Murray, and Anthony! I don't want my voice changed! I really did not mean to make you three run late!
Greg Page: Too bad Greg! This is what you get for nearly making us late for our TV program by sleeping!
Murray Cook: We also had to be delayed by Flora the Door thanks to you and we also had to wake you up!
Anthony Field: When we go home, you will be forced to eat Fruit Salad!
Doctor: The doctor is here.
Memy9909's mom: Change my son's voice because he got expelled from school!
Memy9909 (now speaking in Julie's voice): Oh no! My voice is Julie!
Doctor: How's this?
Memy9909's mom: It's good! Let's go home now!
Memy9909: Wah wah wah wah wah wah wah wah wah wah wah wah wah wah wah!
