After this pic: https://inkbunny.net/s/1456610 Rocket wakes up horrified to discover that dream made him wet his pull-up the worst it's ever been. He's horrified to see that it leaked all over his sheets, his blankets, and even the teddy bear he loves so much. Carefully trying not to leak anymore he slowly gets out of bed. When he's on the ground and stands up his pull-up starts to slide off of him. He quickly grabs onto it before it can hit the floor and make yet another thing he has to clean up. With his paws holing up his soaked protection that didn't protect very much of anything that night he sneaks to his door. He knows he has to get to Groot's room where he keeps his stash of dry gear. He tries to be sneaky, terrified someone will see him until his panic takes over and he decided "screw it" and started running thinking that in the middle of the night would be safer than any other time. That is until he runs straight into something hard and fall backward onto his pull-up with a squish. Rocket rubs his head and wonders what he ran into. He doesn't have to wonder long because the thing he ran into starts talking.
"Rocket? Is that you?"
It was Starlord. He held out a hand to Rocket to help him up, and Rocket took it still a little dizzy from hitting his head. He rubbed his head with both paws and felt his pull-up slip again and he grabbed back onto it in a panic. Only then did Starlord notice Rockets choice of undergarments in the dim light.
"I didn't think those rocket pull-ups were for Groot..." Earlier that month Starlord found Rocket's stash in Groot's room where he hid them and in a panic Rocket sort of threw Groot under the bus saying he was having trouble with not being able to control his sap at night. Groot was mad at first that everyone now though he wore those but being a good friend took the hit for Rocket.
"Hey look we match, we're wearing the same color."
Rocket started getting mad and growled at the remark.
"But mine isn't as yellow as yours is. Haha..."
Rocket had enough and pointed his finger at Starlord. "Look! Not one word to anyone got it?"
"I mean it! Not a single word, or I'll get you understand? I know where you sleep."
With that Rocket grunted and toddled to Groot's room, his face burning red with anger and the fact that someone else knew his secret. Inside he went over to the drawers where he kept his spare pull-ups. While he dug inside he let the one he was wearing finally fall to the floor. As he looked in the drawer he heard Groot waking up form the noise. "I am Groot?"
"It's just me buddy... I had sort of a bad night, and I need a new one of these."
"I am Groot?"
"Nothing much else happened other than Starlord knows my secret now..." Rocket finally found one of the dry pull-ups and stepped out of his wet one before slipping the new one on. His fur was still damp but after the night he had he didn't care anymore.
"I am Groot."
"I don't know if he can keep a secret or not. Maybe he can, or maybe by the end of the week everyone in the galaxy will know about my problem..." Rocket took the wet pull-up and put it in a plastic bag and then put the whole thing in the trash like he'd done every night now for the past year.
"I am Groot."
"I should just tell my secret and get it over with? What if everyone makes fun of me? I already have enough trouble getting respect when I look this cute. No one will ever take me seriously again."
"I am Groot..."
"I am NOT overreacting. Look I don't want to think about it anymore okay?" Rocket turned to go back to sleep in his own bed but then remembered he couldn't. "Uhh hey buddy? Can I sleep with you tonight? I sort of wrecked my bed..."
*sigh...* "I am Groot..." Groot probably only accepting because Rocket had already wet and he was probably good for the night.
"Thanks so much!" With that Rocket dove into Groot's bed excited at the sleepover type of situation. Groot sighed and climbed into bed too. "Night Groot."
Groot only grunted too tired to say anything else and soon drifted off to sleep right behind Rocket.
