Voice Block

An unknown voice was once discovered from a black and yellow object shaped like a cube. There are no photographs known from this object. When nearby this object, it will produce strange noises most likely relatives. When tested, the "Testers" arms shook rapidly, and after about 15 minutes, the testers arms turned black and yellow for a few minutes, then after another 15 minutes, testers tried pulling their arms off. Of course, it didn't work, but another minute passed and they started to turn into black and yellow cubes and were immediately put into the hospital then it wore off after 12 hours.
All testing since had been most likely rejected.
But eventually another test happened where they use it against SCP-173.
This testing was failed as SCP-173 had no ears and was immune to such tests including Voice Block.
Then, about 7 hours after going against SCP-173, it grew to 10 Feet tall.
The Voice Block was immediately placed in another cell, which one of the transporters suffered from the same arm infection as the testers.
After knowing the dangers of this block, 82 percent of SCP staff in the area voted to move Voice Block to a large cell in Hawaii. All info past this is unknown.
