They were both electrocuted and they died. On the news the next day, there was a story about two adults who were found fried at the bottom of the swimming pool. Police suspected they had fallen into the pool during a lightning storm, since Diego had taken the box away and hidden it in his house.
The police also discovered that the adults that had died were the parents of the girl that had been stabbed by Diego, and they immediately knew he had something to with the deaths.
The police started knocking at Diego's door three days later, and he hid all evidence that he had been planning another murder. He put on a wig and answered the door with a fake smile. He greeted the cops and they said that they had tracked the recent deaths to his house.
He battered his eyes and laughed, saying that he didn't kill anyone but his sister Alicia might've. The cops thanked him and rushed over to Alicia's house with batons and handcuffs.
Diego smirked mischievously and pulled out his murder plans. He was going to murder Boots' father just for the fun of it. Two days later he approached the building sight with a knife in his pocket and a smile on his face. It was fake, obviously.
Boots' Dad greeted him and asked him if he wanted to help him build a bridge, not knowing it was Diego who had stabbed his son.
Diego laughed and pulled the knife out, and Boots' Dad's eyes widened almost comically. He began to run, but Diego threw the knife and it stabbed him right in between the shoulder blades. Diego walked away with a smirk on his face.
The rest of the construction crew all ran towards the scene as Boot's Dad attempted to tell them who caused his demise. Diego quickly called the cops to cover his tracks, then he ran towards his house and locked himself in his room.
Laughing maniacally, he pulled out his murder plans and started reading through them. He chanted a special chorus and suddenly everything went blank.
When he woke up, he saw Daddy Pig watering the garden while stuffing his face with a chocolate muffin. He gasped when he saw Diego's cold eyes staring into his soul.
Daddy Pig offered him some muffin, and Diego pounced on him, stuffing the muffin into his mouth so that he choked and died.
Mummy Pig ran outside when she heard her husband's muffled screams. She gasped, seeing Diego stand up and pull out an axe. Mummy Pig slammed the door and locked it, telling her children to get inside their rooms.
Diego had planned this for ages. He was going to travel to every single dimension and kill every single cartoon character possible so that he would be the only one.
He started banging on the door to the Pig's house, calling, "Little Pig little Pig, let me in." However, they could not hear him over their cries. Although Mummy Pig did not truly love her fat husband, she did love her children and herself. Diego didn't give up, he continued to smash on the door with his fists until he eventually just decided to smash it down with his axe.
With one heave of his axe the door crashed down and Diego stepped inside. Mummy Pig screamed and ran down the stairs with a knife in hand, desperate to save herself.
Diego grabbed her wrist and slapped the knife away, and it slid across the floor. The Pig screamed in terror as Diego grabbed the side of her head and jolted it in the wrong direction.
Her lifeless body fell to the ground dangerously fast. Diego sprinted up the stairs, making sure his footsteps were loud. He was overjoyed when the kids screamed their last scream.
He rushed into their room and grabbed George's stuffed dinosaur, ripping its head off and putting a bomb inside. He threw it at the young children and chanted the chorus again, disappearing just as the bomb went off.
When Diego appeared in the SpongeBob dimension, he was covered in Peppa and George's blood. He heard the Sponge's famous laugh, and grinned evilly. He started skipping towards SpongeBob and Patrick.
They were blowing bubbles and laughing outside of SpongeBob's pineapple. They asked Diego if they would like to join him, but he just popped the bubbles they had blown and laughed.
"I don't want to join you," He said. "I want to kill you!"
Patrick laughed, dumbfounded. Diego sighed and grabbed them both by the necks, carrying them to the Krusty Krab where he smashed their heads against a table repeatedly until they died.
Mr Krabs ran towards Diego, yelling at him for getting blood on the table. Diego laughed and cut off his arms, and he died of blood loss. Squidward ran out of the kitchen and gasped when he saw everyone dead.
Diego handed him a knife.
"Join me, Squidward," He smirked. "We can become the most famous cartoons in the universe!"
Squidward was lost for words. It was an honour to be offered such a thing, but he kindly rejected, saying he would prefer not to murder anyone as he might get arrested.
"We will be dimension crossing." Diego explained. "We will not be arrested."
Squidward looked at the corpses of his "friends".
"I still don't want to do it." Squidward said crossly.
Diego shrugged and penetrated Squidward's body with the knife a few times, then left him to die right there in the Krusty Krab.
"Now I'll be the one who dabs," Diego said evilly. He dabbed, although, it was horrible.
"MY EYES!" Screamed a fish. Diego growled and through a dagger at him, and it went straight through one of his eyes.
Next, Diego went to the Chum Bucket where Plankton and his computer wife Karen resided. He smashed the computer to bits, and Plankton ran in angrily.
"What are you doing in my house?!" He exclaimed. He saw Karen's body lying on the floor.
"You killed her!" He said, tears forming in his eyes.
Diego just laughed. "I know, brilliant, right?"
Diego slowly stepped towards the small green creature and raised his foot.
"Are you ready to join her?"
Plankton screamed as Diego squashed him, ending his life. Diego ran to Sandy's dome and smashed it unexpectedly. A shard of glass sliced Sandy's back, and she screamed in pain, but then she choked on the water and drowned.
Diego's laughter was interrupted by police sirens, and he quickly chanted the chorus and disappeared.
He looked around, desperate to know where he was now. He smirked, seeing a peach house in the distance. He saw a pink car pull up in the driveway, and a yellow man walked out, chewing on a donut.
Diego ran towards him and stealthily took his keys out of his pocket. Homer didn't notice. Diego put the keys in the ignition and started the car. Homer screamed in terror and dropped his donut as the car sped towards him.
Diego smashed through the house, crushing Homer. He jumped out of the car and smirked as Homer's blood covered his shoes. He walked inside the house, where Marge was coming to investigate.
"Oh my goodness!" She exclaimed, seeing Homer's corpse.
She saw Diego and saw him hold the keys in a violent position. She rushed up the stairs, locking her and her children in her bedroom. However, she realised she had forgot about Maggie.
She called the baby's name out, and Diego bashed on the door. He pulled out his axe, the same one he had used to knock down Mummy Pig's door. He broke his way into Marge's bedroom, and she hugged her children tightly.
"Take Lisa first!" Bart yelled.
Lisa shoved him and they started cat fighting. Diego cracked his knuckles and punched Marge in the jaw. She clutched her mouth and her children yelled. With one clean swing of his axe, Diego sliced off Marge's hair.
She screamed again and he swung at her once more, this time aiming for her neck.
Blood sprayed all over Bart and Lisa. Marge's decapitated head rolled along the floor. The kids hugged each other, and Diego pulled out his knife. He slowly walked towards them, and stabbed them both in the neck.
Next, he walked towards Maggie's room. She poked her head over the top of the crib. Diego took her out and rocked her back and forth in his arms, and she fell asleep. Then he chanted the chorus once again.
Diego and Maggie appeared in the Adventure Time dimension. Diego smirked. He had been waiting to kill Finn and Jake ever since he found out he could dimension cross. He walked towards the tree house slowly, pondering more ways to kill people.
