It's Arlo's 16th birthday and they are having a party in Bruce Wayne's mansion. Well that would be happening, if the joker didn't show up. Batman and Robin were off doing a mission leaving Arlo, Alfred, Barbara and Harry Styles in Bruce Wayne's living room. "'Appy birthday Arlo!" Harry mumbled as he ate cake. Arlo didn't really mind not having Robin and Batman there, it was nice not to hear constant chaos on her birthday. What she was bothered about were the maybe 10 presents sitting in front of her that she couldn't open until they both arrived. Alfred entertained the group for a while by performing juggling tricks as the hours went by.

After maybe three hours Barbara stood up, "well I'm really sorry, but I do need to get a good sleep to get back into work tomorrow, maybe we can open gifts another time-" it was right at that moment that Batman and Robin crashed through the glass window. Barbara sighed and sat down again "We're here!! :D" Robin exclaimed and promptly started to pull confetti out of his pants  "Happy birthday Arlo!!". "Alright I need to take a shower and then go to sleep" Gruffed Batman "what nooo you must join us, Brucey will be here soon right??" Harry looked up at Batman "Uhhhh yes, but I'm tired and it's fine you guys can open gifts without me" Batman ran out of the room. Afred cleaned up the mess whilst Robin went over the fight in immense detail. 5 minutes passed and Bruce Wayne entered the room. "Brucey!" Harry exclaimed and got up to hug him. "Hello my friends" Bruce smiled as he hugged Harry and sat down. "Let's open those presents shall we" Arlo's eyes lit up, finally.

The evening lit up with light and laughter as Arlo opened each of her individual gifts. She got a pocket knife from Barbara, some jewellery from Harry, matching t shirts from Robin, a few books from Alfred and an assorted variety of gifts from Bruce Wayne, including a new phone. Finally they had reached their final gift, it was from Batman. Bruce had muttered some excuse about needing the bathroom and left. The gift was a small box with a lid, Robin bounced up and down next to Arlo as she opened it. When she had unveiled the gift, he squealed "CAR KEYSSS!!". Underneath the car keys were instructions stating to go to the car port that was in the Batcave. After Arlo told them what was on the note, they all went down into the Bat-cave, Arlo was extremely excited. In the Batcave there it was, a brand new black non-brand specific car, standing next to it is Batman. "Happy birthday kid" Batman smiled. Robin, Arlo and Harry all gasped in unison. "Is it really mine??" Arlo asked in disbelief  "yup all yours" Batman said. "But I can't drive" she said sheepishly, still staring at the shiny Lego vehicle. "I- i mean Bruce will give you driving lessons, Harry will be joining also" "HEY!! I drive better now, why do I still need lessons from Brucey" Harry sulked "better is still not good" Barbara chuckled. "Thank you so so so so much" Arlo hugged Batman "no problem kid", "dad! Can I have a car when I turn 16??" Robin asked excitedly, Batman laughed "we'll seee".

After another hour of festivities, the party had come to an end. "I hope that you found your birthday, errr how do the kids say it pog" Alfred said, this was quickly followed by Robin whispering in Arlo's ears "I taught him thatttttt". "Thank you everyone, this is the best birthday I've ever had" Arlo said. "Bye bye Arlo luv" Harry hugged her as he left, "goodbye Arlo" Barbara waved her goodbye. Arlo was incredibly thankful for the evening that she just had, she wasn't lying, her parents were always too busy to do much of a celebration on her birthday, sometimes they didn't even acknowledge it, this really was the best birthday ever.
