Before "they" extinct (a Splatoon fanfic)

Prologue

"Get over here, you stupid Octotrooper!" a voice yelled. 

A helpless Octotrooper ran as quick as he can with his tiny legs while an Inkling in green chased after him. 

Only if I can get rid of her forever--! the Octotrooper thought. 

Then an idea crashed in his tiny brain like a train. That machine the scientists had been working on... I know what to do now!

The Octotrooper made his way to the unfinished machine, which looks more like a random vault in the middle of a platform. He hide behind the 

"Hmm... a vault! Try finding a key!" an old man's voice rang within the Inkling's headsets. This old man was none other than Cap'n Cuttlefish, the leader of the New Squidbeak Splatoon.

The Inkling nodded and looked around. The Octotrooper is nowhere to be found... neither a key. However, she noticed a single, obvious crate at one side of the platform.

"Be careful, young one. Octarians might be hiding near it." the Cap'n warned.

The Inkling nodded and carefully approached the crate. She broke it open with her ink shots. Nothing happened. She grabbed the key. Nothing happened either. She walked close to the vault. Nothing happened. At all.

"That's weird." she mumbled. She unlocked the vault, expecting something like a gusher or a jumping pad. But when the vault was unlocked, a hole appeared instead. Inside the hole gleamed a beautiful shade of amber light... just like a sunset.

The inkling stepped forward to check. "I've never seen anything like this before...

Suddenly, she felt a push behind her. Of course, the person who did this is none other than the Octotrooper.

The Inkling screamed while falling down the hole. She heard a voice calling her.

"Ag--&*#^eeeee#&($&nt#*&#( 3- th-thr#%^ree^$%*@^eeeee---?!"

Then everything turned black.
