Fans Say
Lindsay B. - I really adore Amy's voice. It has a cuteness when she does her female roles that shines. When she does Max's voice, she's able to get all of the emotions through clearly, adding the subtle tones that make May's little brother his own character. Max is able to tease and taunt, but with Amy's performance, you can tell that he's proud of his big sister. Through Amy's voice I've grown fond of Max, and it wouldn't be the same without her.
