ON WITH THE STORY BABEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEH

In a giant building were a bunch of scientists. Who worked there to well do science things and idk what they do I'm not scientist so don't bother asking me what they are doing. One of the scientist, by the name of Dr. Ben, worked there. His job was mostly to inspect and study the creatures that were brought in the lab. "Good evening Dr. Ben." A scientist who goes by the name Dr. Rogen approached Ben. "Ahhh good evening to you as well Dr Harold." Ben said with a greeting smile. "How's the research going so far?" Rogen asked. "Well I have discovered that the name of these creatures are called Kraang and that they seem to be some kind of inter-dimensional kind of creatures. From what happened during the invasion it seems as if they have the ability to infect other people which includes humans and possibly other kinds of creatures to become just like them." Ben explained as detailed as he could. Then one of the Kraang hissed at him. "They seem to be naturally aggressive it seems." Ben stated. "I see. Well, for now, we should keep these creatures within their cages and to NOT allow them out at all." Rogen said. Putting his hand on the glass container where 3 of the Kraangs were in. "Hey why don't you maybe help me to do something? There is something I don't really understand." Rogen asked Ben. Turning his head to face him. "Of course I'm coming." Ben answered. Putting down his paperwork and walking out of the lab with Rogen. Closing the door and shutting the lights out.

Meanwhile the Kraang decided to use this to their advantage and try to break the glass case. They were hitting their heads/bodies onto the glass case and the glass was starting to slowly break. They continued to do it harder and faster. Trying their hardest to break it and escape. Finally... they heard a glass shatter. They were free... they let out a single evil grin. They got out of the cages and freed all the animals they had in other cages. The tree of them started to mutate them. Turning into these disgusting kraang like monsters.

"WARNING!" The voice repeated. All of the scientists and workers there were confused and shocked by the alarm. What the hell? What happened? Was it a fire?? That's when the 3 kraang monsters busted out of a wall and had all of the scientists in shock. And as well revealed the many kraang animals they have created. The kraang pointed at the scientists and the creatures attacked. The scientists tried to runaway but it was impossible. They were way too fast for the scientists to escape. The animals started to harm the scientists. Some barely have escaped. The kraang just laughed menacingly.

The kraang left the building, leaving the kraang animal like creatures to finish off what was left of the scientists. They now had to find something else... something that will bring back their king...

The key...
