CHAPTER SEVEN: GRUDGES
What happened that night was between Bowser Jr. and Yoshi until everyone started to realize that Donkey Kong was missing. Unbeknownst to Jr, Yoshi told Mario everything the next morning, and the story soon spread throughout the whole group. Donkey Kong's calculations were partially disproved, but only when Jr. was disconfirmed to be Bowser's accomplice would Bowser's name be cleared, so everyone decided that they should not be too sure about their suspects until Jr.'s fate was revealed.

Diddy was furious. Completely disregarding his own safety, he cornered Jr. after breakfast with the intention of beating up his friend's killer. Hardly a murderous person himself, he wouldn't want to kill Jr, but at least teach him a lesson. The encounter took place in the dining room.
"Come here, Jr," Diddy said threateningly. Jr. looked over.
"What do you want?"
Diddy didn't answer. He ran over and tackled Jr. while he was in his chair, causing the chair to fall onto Jr.'s head and bruise it.
"OUCH!" He picked up the chair and tossed it aside before punching Diddy in the face. The chimp collapsed and took a moment to regain his strength while Jr. stood over him, tauntingly. Suddenly, Diddy leaped up and kicked Jr. in the face with both feet before landing, then did a spring jump and tackled him again. Jr. struggled to free himself until he located Diddy's tail and bit it with all his might. Diddy yelped in pain and released his victim, which was a mistake—Jr. took advantage of the situation and threw a chair at the whimpering Diddy before jumping onto the large table and backing up, allowing room for a full-fledged battle. Diddy understood and jumped onto the table as well, taking his fighting stance and waiting for Jr. to make the first move. After waiting several moments, he decided to throw the first punch, but Jr. ducked and tripped Diddy, who then fell off the table into an overturned chair. The legs poked his back and he screamed in agony, loudly enough for Toad to hear from the kitchen. Toad entered the room to find Jr. kicking the injured Diddy.
"Hey! Guys!" Neither one heard Toad's shouts. "GUYS!"
They looked up for a moment, dismissed him, and continued. Toad took action by jumping into the fray and prying the kids apart for the sake of holding their attention.
"Stop… fighting…" He mustered all of his strength to push them apart. They seemed to calm down after a moment.
"Alright, so… what seems to be the pro—" Jr. and Diddy broke out of his hold and clobbered each other, catching Toad in the crossfire. Toad was thrown about while the children punched and kicked and bit.
"He—killed—Donkey Kong—" Diddy said between attacks. Jr. could not defend himself, but continued to fight. Reluctantly, Toad forced himself to beat the other two into submission so he could break them up, but it seemed to make things worse. Diddy started picking up leftover silverware and jamming it anywhere within reach while Jr. began using all of his force to try to overturn the whole table. Diddy jumped out of the way just as the dining table fell over on top of Toad, who crawled out and found himself showered in chairs and used dishes. The dining room was a complete mess. Unfinished breakfast covered everyone as they thrust their limbs into the other's head. Bowser Jr. met a face-full of soggy cereal as he mashed a blueberry muffin in Diddy's eyes, obstructing his vision. Toad felt something squishy on his large head—he picked it up and realized it was a fried egg. Tossing the food aside, he cautiously made his way in between toppled chairs and broken plates to the main battle. Wiping cold porridge off his face, Toad picked Diddy up by his shirt collar and Jr.'s bandana and pinned their arms to their sides. The commotion ceased; he wiped the muffin out of Diddy's eyes.
"What—is—going—on?!" he panted. The children were silent. "I don't want you two fighting anymore, it won't do anyone any good."

Diddy's spirits did not raise, but he remembered to keep his temper. The three of them knew that Bowser Jr. deserved punishment, but there could be no stop to his behavior. He was a Koopa family member, and was not only expected, but praised by his father for any evil deeds that he could accomplish. In turn, he was much loved by his father, and this feeling was returned by Jr. This bond was what drove Jr. to commit his crime, and while some believed in Donkey Kong's actions, others knew that Jr. was just protecting his father.
