Spike was sleeping, as that was how he spent most of his time, when he was awoken by the sound of a cannon. He opened his eyes and saw before him a small party with Pinkie Pie next to it.
"Happy Birthday Spike!" Pinkie yelled, even though she knew it was not his birthday, Spike didn't.
A grin showed across his face, "Is it my birthday? Wow, I forgot. Guess I've lost track of time." Pinkie put a record on and gave Spike a cup of punch in a magically enlarged cup, with an added anti-spill spell so Spike could drink from it with his shaky hands. While Pinkie got Spike a piece of cake, Spike looked around expectantly
"Are you looking for presents?" Pinkie asked, she didn't have one, only because Spike would forget what he was doing by the time he had unwrapped it.
"Oh no, I'm just waiting to see who's coming, or is this one of those parties where you take me to it?" He asked excitedly, after he ate his cake he continued looking around (after being reminded by Pinkie several time's what was going on) he finally asked her "Did you invite Shining? I think I missed his last birthday and I'm afraid he might be miffed at me." Spike said to a Pinkie who's mane had gone flat. Spike had indeed missed Shining Armor's last birthday party before he had died. It had been something he had regretted, as it would have been the last time he could have seen him, instead he got to see him again in a casket.
"Oh! I know, I'll give him his present!" Spike said suddenly, snapping Pinkie out of her thoughts, he attempted to get up, but failed. He instead pointed to the giant dresser he never used. "Could you grab it for me Pinkie? I think it's still in there. I asked Twilight to put a spell on it so it would stay safe...I....why did I ask her to do that?" he pondered as Pinkie went to the dresser and opened the pony sized door, or at least she tried to, the door crumbled to dust at her touch.
"Wow, has it really been that long?" She asked as she walked in and looked around. Almost everything in the dresser was gone, worn away from thousands of years without physical interaction. Yet, among the dust was a small, nicely wrapped box. Pinkie picked it up and read the attached little tag.
To: Shining
From: Your little Bro, Spike. Happy 83 birthday!
Pinkie, unable to resist the temptation, opened the box and found a little framed picture of a young Shining Armor and Spike. Next to the picture was a handmade card that read, Look what I found! We used to be so young. Lots of love, Spike.
Pinkie wiped her eyes and left the dresser to find Spike had fallen asleep again. Pinkie walked over and patted his snout. "Happy 6,756th birthday Spike" she whispered before she took the box to Twilight.
