As soon as Mikey's last birthday party was over, the prankster began again to count the days of the long wait of a year to enjoy the next one.
Mikey hardly managed to contain his happiness to know that he would soon enjoy a great party to celebrate when he came into this world. But his yearnings began to turn into constant reminders to all the members of his family. They started to get upset at the slightest mention of the long-awaited day of the youngest turtle.
At first, they could ignore him, but Mikey got to a point where his brothers were nervous as hell.
"Raph, do you know what is gonna happen in a month?" Michelangelo had crept up behind the couch where his brother in red was sitting, taking him by surprise. The hot-headed turtle frowned after letting out a short scream of fear. He was about to pounce on Mikey for having interrupted his turn to watch TV.
"I don't know," Raphael responded rudely after rolling his eyes, "Isn't it the fool's day?"
"No hothead! It's the day you have to thank heaven for having had the luck and privilege to have me as your baby brother!" Mikey smiled broadly, seeming not to have seen his brother's furious gesture when he squeezed the beer can in his hand.
"Do you think I'm an idiot!? You've told me more than a hundred times in the last two months. Stop ticking me off, knucklehead!"
"Okay… I get it." Mikey slowly withdrew without turning. Raphael smiled. Maybe, at last, he could enjoy an afternoon without bearing Mikey.
"But remember you have to buy me a great gift!" That voice got him to jump again. Somehow, Mikey had managed once more to get closer behind his brother's back without him noticing.
"Get the hell out of my sight!" The grumpy turtle yelled at his baby brother, throwing the beer can at him. The youngest turtle just stuck out his tongue at Raph.
Donatello was working hard on an experiment in his lab when he was taken by surprise by his younger brother.
"Donnie!" Because of his baby brother's yell, the smartest turtle dropped much more of a substance into the beaker he was using. The mix began to react so violently that it set off a tiny explosion that left his face stained black.
"Mikey! You know better than to enter my lab like that. I have told you million times it could be too dangerous!" Don exclaimed.
"Yeah, yeah, whatever. Let's get to the point," the prankster shrugged, making his brother in purple very angry. "Just remember the great event that will take place within a month, now you don't have much time to get my gift ready and remember you have to give a great speech about how much I contribute not only to this family, but also the world. Get it, Brainiac?" Mikey grinned from ear to ear without much care for his brother's glare at him.
Instead of giving his annoying little brother an answer, Donatello turned around and started rummaging inside one of the drawers of his desk, looking for something.
"What are you looking for, genius?"
"The object that is going to be cataloged as the murder weapon when I stand trial for your murder." The young scientist pulled an old scalpel out of the drawer and jumped on Mikey, who, screaming like a girl, fled immediately from the lab.
After sighing, relieved because he had got rid of Mikey, Donatello dropped the scalpel, but as soon as he did it, his brother seemed to come out of nowhere in front of him, getting Donatello to scream out of fright.
"It seems you want to outdo me in the old art of making jokes. Don't you, Donnie?"
"Get the shell out of here, Michelangelo!"
Donatello slammed the door shut after he shoved his brother out of his lab.
"It seems the others are angry at me, Leo." The jokester complained to his big brother, but Leonardo didn't seem to pay attention at all. He had been meditating. "I just wanted to remind them to not forget my birthday party. It's going to be the first time Casey, April, and my friends from the Justice Force are going to be present. The whole party is going to be recorded for the first time too. I just want everything to be perfect, just like I dreamed it."
"Everything will be fine, Mikey, don't worry, and stop reminding us, we know." Those were the only words Leonardo told him before letting out a small sigh of annoyance because every day, Mikey behaved like that.
Finally, the big day came. Mikey was fascinated by everything: his gifts, the food, the presence of his friends, and especially the large cake baked by his old father's loving hands.
But for some reason, it seemed that his brothers were bored. Perhaps the constant reminders of the youngest turtle had decreased a little the joy in his brothers, but Mikey was too self-absorbed enjoying everything to care too much about it.
Right after, Silver Sentry placed the big cake before the birthday boy, helping the wise rat to take it to the table. Everybody started to sing 'Happy Birthday', and the one who was singing the loudest was Mikey, using a birthday cap, looked at the cake with greedy eyes, enjoying the smell it gave off.
Leonardo and Raphael were next to Mikey, and they looked bored. But at some point, before the song was over, Raphael looked at Leonardo and smiled at him, and gave him a nudge. The turtle in blue knew his grumpy brother was going to play a joke on Mikey, but Leonardo just waited to see what he was going to do.
Exactly when the song ended, Raphael, quickly and quite forcefully, pushed Mikey's face into the cake. A slight bump was heard when Mikey´s forehead touched the table's top. Everybody burst into laughs when they saw that, but Mikey didn't expect it. At seeing that everyone was laughing at him and not with him, the jokester stood up, looked at everyone with anger, and without giving an explanation, he headed to the bathroom and locked himself in.
"Raphael, why did you that to your brother?" The old sensei demanded to know; he was very angry because his impetuous son had ruined his effort when he made the cake. Big chunks of the cake had fallen to the ground. It was ruined.
"Oh, come on, sensei. Mikey did the same to me on my birthday and didn't say a word about it!"
"But on that occasion, you only got a thin layer of frosting on your face, Raphael. Your head didn't go through the whole cake ruining it, and, didn't hit the table either."
After the wait of one hour, Mikey wasn't coming out of the bathroom yet. All the guests retired, leaving the family members alone. The three brothers decided not to talk to Mikey until he wasn't angry anymore.
But as the days passed, Mikey remained locked in his room most of the time. On the fifth day, Master Splinter began to worry seriously about his youngest son. It was unusual his son remained angry for so long, and when he did, he only lasted just a few hours and then went back to being the same as before. Resentment was a feeling that couldn't survive within Mikey's heart.
This was inspired by the scene from season 7 in when the turtles were turned evil, and from Raphael's memories when Raph pushed Mikey's face into his own birthday cake.
And I'd like to thank Rose Black Dragon for helping write it. My mind has been drawing a blank lately. I can think up ideas, but just writing after finishing up some other stories, just needed a break. But I have been wanting to get this out for a while.
