After crashing his ship on Knuckles's island, and Knuckles rescuing him they both notice it's getting late. Knuckles suggests Shadow just stay the night. Shadow nervously resists the idea but Knuckles insists. Even though Knuckles himself is very nervous at his own idea. He's not sure he can really trust Shadow at all. Things don't get any easier that night though when they start fight over one of the most childish things they could of course. Who'd sleep on the top bunk.
"I sleep on the top bunk." Knuckles started.
"I'm the guest, it should be ME who sleeps up there."
"This is MY house though so I should sleep up there."
"Where you SHOULD sleep is on the bottom so you won't pee on me from up there."
"What did you say?", Knuckles asked angrily his face turning even redder than normal.
"You heard me. Everyone knows about your bedtime problem. And what you wear for them." Shadow said with a sly grin.
"Yeah, well, that just means I can sleep on the top bunk and you won't have to worry." Knuckles tried to rationalize.
"Man your really annoying Crinkle Knucks."
"WHAT DID YOU CALL ME!?!?" Knuckles exploded hearing the nasty nickname his enemies gave him when they found out about his problem.
"Crinkle Knucks. That's who you are after all."
"Who the hell do you think you are calling me that?!"
Then Shadow crossed the line by grabbing onto Knuckles's pj pants and pulling them down revealing his bedtime gear. "You sure look like a Crinkle Knucks to me."
With that Knuckles's temper barely hanging on up to now totally broke loose. Knuckles yelled and tackled Shadow. With that the two had a full on breaking things fight in the room as they rolled around punching and kicking each other. Knuckles was still the better fighter though and eventually pined Shadow in place under his padded butt.
"Now.", Knuckles said with an evil smile. "Like pantsing people eh? Let's just see how YOU like it!"
With that he grabbed onto Shadows own pj pants and got ready to pull them off. Shadow saw this and panicked. "WAIT! DON'T!" But it was too late as Knuckles yanked the pants off so hard he fell backwards a few feet away, and Shadow's own diapers were fully exposed. Knuckles could only stared in silence for a few seconds.
"Wait... You too..?" Shadow's face was fully red by now and he was so embarrassed he could only muster a nod. Knuckles growled angrily and threw Shadow's pants at his face. "Hypocrite." He spat. "Making fun of me for the same damn thing."
"I was embarrassed..."
The two then just sat there in their padding in silence feeling sorry for themselves.
