Here it is the first episode! Song used here is Bad Day by David Powter.

Bruce was just heading downstairs to train when a couple of voices stop him in his tracks. Taking a couple of steps back, he leans against the door of Dick's bedroom and listens.

[Dick] Where is the moment we needed the most? ([Jason]most, most, most)
You kick up the leaves, and the magic is lost ([Jason]lost, lost, lost)
Ever since he was little, Dick had always been extremely hyperactive and full of energy. Never once would he frown, always smiling even in times of trouble. Perhaps it was that little energy of his that gets him out of trouble most of the time and as a result, it is Jason that takes the fall.

[Jason,Tim and Damian]Ooh

Still he never imagined that Dick could sing as well as he is singing now. Dancing is not that much of a problem since the kid is a circus brat and took up dancing lessons as a child. That explains his non-stop energy and crazy overdramatic antics.
[Dick]They tell me your blue skies fade to grey
They tell me your passion's gone away
And I don't need no carryin' on

Jason on the otherhand is a elementary school hustler though Dick himself has traces of that. He is loudmouthed, just as dramatic and extremely sassy when it comes to authority figures though of course the two people he fears the most were Daddy Bats and Alfred.
[Jason, Tim and Damian] Ahh

[Dick] You stand in the line just to hit a new low ([Jason]low, low)
You're faking a smile with the coffee to go ([Jason]go, go)
Timmy was the quieter one who rarely talks and almost always chastises his brothers even though really, he is no different from them and causes just as much, if not more mischief than they do. He is the smart kid and junior detective and always invents the craziest over the top gadgets, some of which Bruce occasionally borrows.
[Jason, Tim and Damian] Ah, ooh
Lastly, Damian aka Little D or Baby Bat. He is a cute yet slightly moody and cranky kid who whines over the littlest of things and mostly eats and sleeps but still does his work diligently anyway. Bruce cannot help but wonder how he ended up with these four lovely yet crazy kids. Nevertheless, he is glad to be a father as despite all the craziness in his life, he knows he has people to come back to, people who would still love him no matter what.
[Dick]You tell me your life's been way off line
You're falling to pieces every time
And I don't need no carryin' on

[All]Because you had a bad day
You're takin' one down
You sing a sad song just to turn it around
You say you don't know
You tell me don't lie
You work at a smile and you go for a ride
You had a bad day
The camera don't lie
You're coming back down and you really don't mind
You had a bad day
Oh, you had a bad day

[Dick] Mmm, oh, yeah
Mmm, oh, mmm

[Jason, Tim and Damian] Ooh
Bruce hums and bops his head along to the song. He is surprised that Dick is dominating most of it, though that should not really surprise anyone since Dick has made it a point to be the main star. He feels a hand on his shoulder. He turns around to see his ever faithful butler and father figure Alfred standing beside him with a huge smile on his face. "They sing beautifully." Says Alfred. Bruce nods and smiles. "Couldn't be more proud of them."
[Dick]Well, you need a blue sky holiday
The point is they laugh at what you say
And I don't need no carryin' on

[All]You had a bad day
You're takin' one down
You sing a sad song just to turn it around
You say you don't know
You tell me don't lie
You work at a smile and you go for a ride
You had a bad day
The camera don't lie
You're coming back down and you really don't mind
You had a bad day

[Dick]Ooh, a holiday

[Jason, Tim and Damian] Ahh

[Dick]Sometimes the system goes on the blink
And the whole thing turns out wrong
You might not make it back and you know
That you could be well, oh, that strong
And I'm not wrong

So where is the passion when you need it the most? ([Jason]most, most)
Oh, you and I
You kick up the leaves and the magic is lost ([Jason] lost, lost, lost)

[All]'Cause you had a bad day
You're takin' one down
You sing a sad song just to turn it around
You say you don't know
You tell me don't lie
You work at a smile and you go for a ride
You had a bad day
You've seen what you like
And how does it feel for one more time?
You had a bad day

[Dick]You had a bad day

Both Alfred and Bruce walk into the room and clap for the boys, catching the kids offguard. "Bravo young masters!" says Alfred. Bruce merely nods and smiles. Damian runs towards his father and gives him a huge hug.

Bruce chuckles and lifts up the little baby. "You ok Little D?" The kid pouts. "Is it bad if I want a hug?" The others giggled and run over to their dad and give him a hug. "We sang this just to cheer you up dad because we have noticed how sad you have been feeling lately." Says Tim.

Jason then pulls Alfred forward to join in the group hug. "Yes daddy, we want you to smile and not feel sad. We want you to be happy." Says Dick with a huge grin on his face.

Bruce smiles softly. Despite the mischief these four get into, there isn't a doubt that they all love and care for him and at times do that for attention. Bruce sighs happily. "How did I get you kids? I do not deserve this." He says, looking away so as not to cry in front of them.

Damian pats his daddy on the head. "Papa, don't cry." He says in his usual cute voice. Bruce chuckles softly as he absent-mindly wipes a tear away from the corners of his eyes. "God you kids.." The boys all laughed. "Hey dad, how about we head out to see a movie?" Dick suggests. Bruce thinks about that. "You know, that is not such a bad idea. Besides, we have been working non-stop and have never gotten the chance to actually kick back and relax." He says.

Damian pouts. "Pwease no ghost movies or scary movies." He whines. Everyone laughs. "Ok kiddo, no horror movies." Jason pouts. "But I want to watch one!" he whined. Dick glares at his younger brother. "Will you considerate of Little D?!" Jason fumes. "Oh like you are ever considerate of anyone PrettyBoy?!" he retorts.

Bruce shakes his head and leads the two younger Robins away whilst Alfred tries to settle the fight between the two oldest ones.

Here you go. Some silly Batfam fluff. Bruce is one lucky dad
