## Synopsis

Dafa and Puti are surprised by the appearance of an opponent named Bu Unyi, who makes deafening sounds to attack people. They ask Robo to help them analyzing Bu Unyi's powers and abilities.

## Plot

A music teacher is corrupted by Ira Sukma and turns evil. Then, a mysterious message pops up on the screen at the heroes' headquarter, which contains the face of the music teacher in the form of Bu Unyi.

> **"Hello, my sweet children. I am Bu Unyi! I exist because of the vibrations of things around us. Everything I vibrate will be the source of the sound!”** - Bu Unyi
>

Bu Unyi plays a guitar that makes a deafening sound to Dafa and Puti, who then ask Robo for help. Robo's analysis resulted to the conditions for the occurrence of sound, namely:

1. There must be a source of the sound, which is Bu Unyi's guitar.
2. There must be a material medium around Bu Unyi to pick up the guitar's energy and then propagate it in forward direction.
3. There must be a receiver, which is the heroes' ears.

When the sound of the guitar is getting more deafening, Robo re-analyze the pattern of the attack, starting from the vibrating body. Robo finds out that the sound is traveling through the air as its wave to the ears. Robo declares that Bu Unyi is highly dangerous.

Bu Unyi then shows off her abilities to control frequency and amplitude. Then, the screen at the headquarter shows Bu Nana is trapped in a cage, asking for help. However, Dafa, Puti, and Robo can't hear her voice. Bu Unyi gives them a riddle to solve.

> **"If you want to hear her voice, then solve this riddle: it's not about the loudness or quietness of the sound, it's about the highness and lowness of the tone."** - Bu Unyi
>

Robo helps Dafa and Puti to adjust the frequency so many times to reach various soundwaves. It turns out, Bu Unyi is playing with Bu Nana's soundwave so they can't hear her voice, until the umpteenth try when they finally can hear her voice.

> **“Kids, help me! I'm trapped at the zoo!"** - Bu Nana
>
>

Robo analyzes the video sent by Bu Unyi, which leads them to a clue left by her to save Bu Nana.

> **"As long as there's sources of the sound, mediums, and ears, I am unbeatable!"** - Bu Unyi
>
>

Dafa comes up with a strategy to attack Bu Unyi's weakest point, starting from avoiding the sound. However, this first strategy failed when Dafa realizes that everything around him can be the source of sound. Puti helps planning the second strategy, which is to make the medium disappeared. However, it also failed because if they make the air disappeared, then the animals at the zoo won't be able to breathe.

Robo then analyze Bu Unyi's statement about ears are needed to receive the soundwaves that are traveling through the air. Puti comes up with a plan to cover their ears.

> **“Why don't we make an ear-covering tools before we fight her?”** - Puti
>
>

Dafa welcomes this plan with excitement.

> **“That's a good idea, Puti! Bona and I will try to make the tools.”** - Dafa
>

Dafa then ask Puti, Made, and Dira to prepare to fight Bu Unyi. Meanwhile, Dafa will meet Bona to create the ear-covering tools. They will all meet at the zoo to fight Bu Unyi as well as save Bu Nana.
