Tonight, in the treehouse there was a ten-year-old young boy, Scott Jones who was working in his secret chemistry. He used a sugar cube to grow a sugar tree, but then it turned out that was a donut tree and grabbed one of the donuts which he likes.

"Completely, the flavor is called Trout." smiled Scott. Back at the lab where Scott suddenly to takes out a heart-shaped tablet in every color, he likes inside a pouch. "Okay, just one try," murmured Scott, he takes out a jug of water and the tablet drops into the water.

Then, the water is carbonated like Alka Seltzer and changes color that matches its flavor. "Eureka!" he cheered and take out an empty glass while pouring the drink on the glass.

Unbeknownst to him, there was a four-month-old infant little girl named Rachel wears baby clothes who came out of nowhere and spot that Scott was drinking.

"Rodney!" cooed Rachel, Scott turned around to see his sister.

"Not now, Ray, It's not your business. These are Fizz Bop Rocket Pop, a flavored drinks-like sodas which contain a total of 14 different varieties," explained Scott.

"Rodney!" cooed Rachel.

"I knew it sounds terrible, but I'll show the labels," replied Scott.

He pulls the tables full of glasses with labels such as Grape Julep, Wallpaper, Dog Smell, Festive Forest, Riverbank, Leonard, Eggplant, Mouthwash, Tree Bark, Barnyard, Squid, Rooty Tooty, Dirt (a seasonal flavor) and also Carpet (a holiday flavor).

"Yuck!" cooed Rachel, disgusted.

"Don't worry, I got backup flavor I made," replied Scott, he pulls another table with glasses with labels such as candies, chocolate and gummies and gums.

"Hmm." satisfied Rachel.

"I'm going to celebrate Fudge Day by myself," said Scott, but when he saw Rachel grabbed one of his flavored drinks, Strawberry and chugged it which she causes a hiccup. "Rachel!" he was very angry at his sister, scaring the hiccup away and made her crying.

Rachel sees the box of fudge that came from the table and eats them all which Scott was frustrated over her eating his favorite candy. Suddenly, Rachel goes sugar buzz and insane, yelling extremely loudly and causing a rampage around his lab.

"Noooooooooo!" screamed Scott.

Then, a Pixar villain-turned-antihero named Syndrome comes to visit with his young connection a Dreamwork orphan named Sherman Peabody who sees that Scott was tired of his sister.

"Oh hi, Sherman and I were working to helped you." greeted Syndrome.

"Oh hi." greeted Scott, then Rachel swallows the Fizz Bop Rocket Pop whole.

Due to consumes the Fizz Bop Rocket Pop, Rachel felt something so unusual in her stomach, she started to bloated so touch like a bowling ball and she floated like a balloon which shocked Scott who sees her.

"Oh no!" Scott was very angry at his sister that she didn't know how she put the water first.

"Well, let me explained that according to my research that there is one thing about two flying creatures who are obsessed with all kinds of candies, in binomial name, Candius spritius," he explained to Syndrome and Sherman Peabody.

"And what happened?" questioned Syndrome.

"Let me tell yaw, I'll show you," explained Scott, he goes to the left side which there was cloth-covered something. He pulls it off which revealed that it was a giant rock candy that used a source of power.

"What, We never heard of that?" confused Syndrome.

"Of course, I'm professional and my parents won't let me have candies because I'm ten and I have to take care of my sister, I hate and I never accept her as my own," said Scott.

Unbeknownst to Scott who was talking about his discussions, Rachel was floated free outside of the treehouse, but then, there was a branch that was spiky which pops Rachel to flying away into the air like a balloon while she cried and screaming that alerted Scott who turned around to see his sister.

"Rachel!" shocked Scott, horrified.

Scott went out of the treehouse to chased after his sisters through the neighborhood which causing chaos around the area, scaring the neighbors who see her and they run off in panic. Then, it reached toward the Police Department where a cop named David Jones who sees the kids in confusion.

"Rodney!" shocked Jones.

"Hi..." sighed Scott, Rachel files through the window, breaking the glass when she went inside.

"Rodney, why your sister is flying like a balloon?" questioned Jones.

"Oh that was one of my experiments, Fizz Bop Rocket Pop," explained Scott, Syndrome and Sherman come up to see that Rachel had wreck havoc incidentally.

"Scott, I don't think that Rachel got hurt wouldn't you." worried Syndrome.

Then, a shriek was heard from the precinct, it was an industrial heir, Ryan Waygetter who was chased away by his adoptive sister when she morphed into his worst fear via her powers, his invention, Mommy Furbytail. Ryan jumped toward his adoptive family and hide behind Scott.

"Please help me!" begged Ryan, frightened as Rachel turned back her true form again and laughed at her adoptive brother.

"Rachel!" grumped Scott, he walked toward Rachel, grabbed her by her waist with his hands and carried her up.

"Roderick Prescott Jones, didn't I tell you not to feed your sister some candies," said Jones.

"Yep, but I was so angry at him for causing troubles," replied Scott.

"Yeah, you almost scare me with the fear-inducing powers that can turn herself into worst fears she needs to scare us all," said Ryan.

"I know, I got frizzled hands when I was working on my projected product," said Scott, Rachel sees the Fizz Bop Rocket Pop, swallowing it and floated again like a balloon.

"Rachel!" exclaimed Jones.

Then, a male hyena cub came out of nowhere and whereupon he rescues the baby by jumping up into the sky, grabbed her and forced her floated down which Scott catches her.

"Sorry." sighed Scott, just then, a trainee cop armed Luke Fernandez who brought the box the calamari rings and canned meat.

"Luke, you forgot the antidote!" warned Scott.

"What happened?" asked Sherman.

"Well, It all started when because of the experiments." explained as the flashback interlude begins.
