Note: This takes place after Darkar's Revenge.
It all starts at Lisa's lab.
"Excellent!" cried Lisa. "My new growth formula is finally ready. Now to choose a viable test subject."
Lisa spotted a baby gorilla. "Ah, Bobo."
Bobo, a gorilla, showed up.
Lisa injected it into the gorilla, which caused it to grow. The gorilla was enormous.
The 50-foot-tall gorilla roared.
Luna walks in and asks, "Lis, what's happe..." She notices the giant gorilla. "WHOA!"
Luna screams as the gorilla grabs her, and the gorilla escapes.
"Lisa, what happened!?" yelled J.D.
"I might have made an error," Lisa admitted.
"What did you do?" Varie asked.
They see Bobo giving flowers to Luna.
"Thank you," Luna replied, "but I don't accept gifts from strangers."
"Hey, I think he has a thing for Luna," Rachel observed.
"He sure looks like it," J.D. replied, "but how did Bobo get so big?"
"What a time to develop a crush," Rachel remarked. "And I do mean crush!"
"No kidding," J.D. replied. "Lisa, what did you do to make Bobo so big?"
"It was all part of my experiment for my new Growth Formula," Lisa explained.
"Growth Formula?" asked J.D. "That's so cool!"
Bobo hooted and extended his hand to give J.D. a hive-five.
"Yeah," J.D. agreed.
They exchanged high-fives.
Bobo then took off with Luna.
"We have to stop the ape before it terrorizes the neighborhood!" Rachel shouted.
"Yeah!" replied J.D.
He took out his cell phone and dialed a number. "Ms. Rita, fire up the biplane. We have to save Luna!"
The ape messes with Luna's hair.
"Hey!" cried Luna. "Stop doing that!"
When the police showed up, Bobo began climbing the tallest building in Royal Woods.
That's when Rita and J.D. arrived in a WWI-era biplane.
They circled the building while Bobo was on top of it.
"All right, J.D., we're closing in," Rita ordered. "Get ready to fire."
J.D. responded, "You got it."
J.D. pulls the trigger on the gun and fires. While firing, he laughs like Peter Griffin.
Rita pulls out a mini-gun and fires. "Giggity Giggity Giggity Giggity Giggity Giggity Giggity Giggity Giggity!"
The bullets hit the building, pelting Bobo, and he dropped Luna, who was still hanging on. Bobo roared as Luna realized it was a long way down.
Rita fired the planes' machine guns at Bobo, and they flew around him, causing him to roar once more. J.D. fired a shot from behind at Bobo.
"Eat Lead, King Kong!" shouted J.D.
Bobo swung at the plane, striking the wing. They sputtered and spun, but eventually regained their momentum.
Rachel and Sam flew over, and Sam grabbed Luna before taking off.
Rita fired at Bobo, who attempted to swipe them again, but they dodged and J.D. fired from behind. They circled back and fired again at Bobo, causing him to fall off the building and land with a thud on the street.
"Geez!" shouted J.D. "That must have hurt."
"It sure did," Rita replied. "Let's land."
When they landed, they noticed Sam had rescued Luna.
J.D. praised the girls, saying, "Great job, girls."
"Thanks, J.D," Rachel replied.
"That was awesome flying," Sam added.
"Thanks, Sam," Rita replied.
Bobo stood up and noticed J.D. He suddenly returned to his original size.
"It seems Lisa's growth formula is only temporary," J.D. observed.
J.D. picked up Bobo and handed him a banana. "Sorry about that, Bobo. No hard feelings."
"That's alright, J.D.," Bobo replied.
"So, how was it to be a giant?" J.D. asked.
"It was awesome," Bobo remarked. "I loved it."
"I believe it," J.D. replied. "You might say that all of this was a fight of gigantic proportions."
They all start laughing.
THE END
