A Mad Scientist's Guide to Building an Alien

(This is for a scifi contest)

"C'mon, Taurus."
"Leo, please! We are going to space for the first time!"
"And?"
"Mom and dad told us to be on our best behavior. We can't be our weird selves around their colleagues! Especially you!"
"You need madness in order to achieve greatness."
"But that much!"
"Shush!"
I stuck a chocolate bar into my mouth and pushed my equipment across the launching bay. Taurus followed with his equipment as well. I put my hot pink-and-orange ombré hair into a bun, since it's so hot in Houston. As soon as all the equipment finished loading, Taurus and I put on our astronauts suits and went inside. There was a red headed man inside, who seemed a few years older than me. His name was Captain Smith. He lead us inside, and helped us with our stuff. We soon blasted off into space.
I wondered around on board, thinking about the possibilities I could do on Mars. The "martians" consisted of a human like species, 4 animal-like species, and 15 plant species. They were hidden for so long because they lived under ground or on certain spots of the surface. These species intrigued me, which is why I immediately accepted my parents' offer to study the different species with them.  I was so bored of messing up monkeys, turtle, Venus flytraps, and countless other life forms, that I almost turned to creating human hybrids.
Almost.
Which is why I'm so pumped to be starting anew on Mars. New hybrids, less getting into trouble.

We landed after 2 days of traveling.
My parents greeted us in their dirty uniforms at the landing bay.
"Hiya mum and dad!" Taurus and I said together.
They hugged us one at a time and asked about our recent experiments.' They then helped us with our equipment. Apparently, there's a breathable and non-toxic atmosphere underneath the surface, so we took off our suits.
As soon as I saw the human-like martians, I squealed in delight. They were tiny, as big as my hand, which made them seem even more adorable. The animalistic Martians were odd looking, and had some resemblance to the animals on Earth.
So much potential.
"Leo did you hear what I said?" Mum's voice disturbed my thoughts.
"What?"
"You do realize the only reason we invited you was so that you could help us study these Martians?"
"Awe I thought it's cuz you loved us."
She sighed and left us to go give a report.
"I know that look.." Taurus said disapprovingly.
"What.." I answered innocently.
"Which Martian animals?"
"I am so glad you asked! The Martian dog and Martian lion."
"Should have known... let's get to buisness."
We quickly got a few of the Martian animals into our lab and got to work. For the first few days, we studied and experimented with  their DNA. Various other scientists came in to check on our work, including our parents. We fulfilled the experiments they wanted, without using live specimen.
But when we were done with those boring experiments, we continued our work on our "project."
"Leo, you can't combine the Martian lion hair chromosomes with Martian dog hair chromosomes! They won't fit! It's impossible!" Taurus argued, when I began to combine DNA.
"T, this is why you are my assistant."
"No, I'm your assistant because you are more interesting than the other scientist. Also, you get a little too crazy sometimes."
"Awh, thanks!" I completely bonded the chromosomes together, holding the DNA stable. "Ta da!" I exclaimed.
"Very well, Nebulas." Dr. Rockwood complemented, as he walked into the lab. We thanked him.
"But what are you going to do with this combined DNA?"
"Well, you see, the lion-" I started.
"Dr. Nebula, you are tarnishing your parents' reputation. Focus on the mission at hand! We don't want your foolish experiments!"
He sternly said, and walked away as I glared at him.
"None of them appreciate our work, L. Mom and dad barely do." Taurus whispered, upset.
"They think I'm a fool-I'll show them I'm a  brilliant crazy fool!" I shouted with pride, making a shocked Taurus almost fall over a cage. "MORE ANIMALS!" I ordered, furiously combining more DNA. Taurus smiled and went  to grab more specimen. The next 2 weeks sped by as we experimented more.
As I combined the DNA from the new animals, I felt as if something were missing.
Then it hit me one day.
A humanoid Martian.
"Taurus! We need a humanoid Martian!"
"But why? We're almost done with the new Martian!"
"Ah, yes, but this synthesized egg needs one last thing, which is the DNA of a humanoid Martian . We also need to fertilize that egg with that specimen, so HURRY!" He ran off, as I prepared the incubator and ate some chocolate. He came back, and we quickly developed pure DNA from the specimen. My dad walked in, and noticed our experiment.
"Wow, almost done!" He complemented, as he looked inside the speedy incubator containing the egg, with the shell encased by pure dark chocolate."So was it easy? Also, what's with the chocolate?"
"Daddy. One cannot simply turn a wrench and create life. There must be chocolate." I answered simply. Taurus opened the door for our mother, who was excited to see the experiment. The other scientists came too, but were here to see the final result. Or rather, my idea failing.
At least that's what they think.
"Taurus, flip the switch!" I excitedly dictated. He flipped the switch, and the incubator began glowing.
After 10 minutes, the egg began to crack. Everyone held their breath, as a tiny purple paw poked out the shell. I squealed, and said, "COME TO MAMA!!" Soon enough, our new Martian came out.
She was beautiful. She had large sharp fangs coming out from her dog mouth. Her red mane and fur contrasted her 4-foot tall indigo body.
Everyone began to applaud and shake our hands.
Until she roared angrily, ready to pounce.
