My Sci-fi Story!

This is my science fiction story! The words in blue were originally from a book:

In the past they had sometimes been treated to strange three-legged creatures from Venus, or tall, thin men from Mars, or even snake-like horrors from somewhere more distant. This year, as the great round ship settled slowly to earth in the huge tri-city parking area just outside of Chicago, they watched with awe as the sides slowly slid up to reveal the familiar barred cages. In them were some wild breed of nightmare--small, horse-like animals that moved with quick, jerking motions and constantly chattered in a high-pitched tongue. The citizens of Earth clustered around as Professor Hugo’s crew quickly collected the waiting dollars, and soon the good progress or himself made an appearance, wearing his many-colored rainbow cape and top hat. “Peoples of Earth,”he called into his microphone. “Welcome to the Sci-Fi Convention!!!” As soon as the rainbow gates opened, the humongous crowd rushed through the doors. Little did all the people, even Hugo know this was an evil alien trap!  Suddenly, the gates were closed with a BANG! Nobody was worried because they were too excited and hyper to see all the cool wacky jetpacks such as the special suicide  jetpack with turbo 3,000 A-70 motors that were programmed to blow up. There were many other exhibits with working time machines and blasters of all kind. In the meanwhile, a sickly throwup colored alien with helicopter blade ears inside a cage used his grappling hook fingers to grapple the pavement. He pulled toward it and broke the cage door. “I wale wawahi i keia puka maikai mea e hiki ia oukou ke hoomaopopo mai iaʻu” said the alien. (Translation: I have been waiting to do this! Come on alien fellows, lets raid the party!) He used his goop gun and melted the cage doors of other strange looking aliens such as an alien who had legs as arms and arms as legs with the special ability to make himself inside out. The group of aliens stole an advanced helicopter with cannons that launched other helicopters onto the ground. The squashed each other into the helicopter while others climbed on the helicopter blades. The helicopter zoomed, flinging aliens on the helicopter blade in all directions, and crash landed into the Science Convention. The sickly green alien, or the grafard, pulled out a microphone and yelled, “Hoomana aku i ka mana o ka malihini pae, F.A.R.T. E ku nei no ka mea, momona malihini hoʻi i keia la ma ke ala” (Translation: Bow to the power of the alien group, F.A.R.T. That stands for fat aliens return today by the way.) “NO WAY!” Yelled some random guy. “Don’t say that, you dunderhead! He could have spared our sorry lives!” “Oops.” “Oukou e ae aku i ko makou inaina laila! Ke ahi i ka helicopter pū.” (Translation: You shall suffer our wrath then! Fire the helicopter cannon.” “Yae, yae ris!” exclaimed a blood red alien named rarered that kept on picking up his eyes that dropped. (Translation: Aye, aye sir!) BOOM! A helicopter flew out of the right cannon one feet away from the helicopter and fell down. Kabloosh! The helicopter blew up. After the smoke cleared, the people were looking at the helicopter, dumbfounded. “Oh pono, manawa no ka manao B!” (Translation: “Oh well, time for plan B!” “Uh, what exactly is plan B?” asked an alien named tuto. “Kjjhgdshgshgjsfdj?! Hufhgdfkgdh. Ghfhviervuhfj vbgusbfuvhdghbfshjvh hvfdvdf hvfdsvdf. Pfft. ” said grafard. (Translation: Didn’t I already explain it to you? Oh wait, I didn’t. I guess I shall get the super jetpack.) The grafard went over to the super suicide jetpack and strapped it on to himself. Then he flew up into the air. “Nhhfjdhjsrfkrghsrgsrhgf! Pfft.” (Translation: Now I shall rule over the world!) He was going to say something else, but he never got the chance. The jetpack blew up, but good thing he wasn’t harmed by explosions. He flew 400,000,000 feet into the sky and disappeared. “Now that our boss is gone, what should we do?” said teto. “I guess we try to blow up ourselves into space too.” Said teto 2.  They each grabbed a different kind of harmless bomb and blew themselves into the air with a series of BOOMS and BANGS. There were a few kablooies, but they all disappeared into the sky.
