A New, Mute Friend

A New,Mute Friend is about Marianna Cruz,a new neighbor of Phineas and Ferb from the Philippines,is too shy to hang out with the other kids,because she's mute. If she wants others to understand silent language, she needs help from her sister, Alliah Cruz. Alliah,who became friends with Phineas and Ferb quickly,reached their help to create a device that can translate silent language to regular voice,which it worked properly (except for the robotic voice Ria [Marianna's nickname] hates).
