In a few days Bubble was healed, and when she woke up she was greeted with a "How are you feeling?" from the nurse and a "You took out a whole camp of enemy soldiers, you know," from Whirlwind. "Fine," said Bubble with significant irritation, "And I don't care. Leave me alone." "Remember what I said yesterday?" asked Rainbow, flying over to Bubble's bed and sitting at her bedside. Bubble scanned her memory, and then she recounted the events. Rainbow asking her the same question she'd asked Pinkie, Bubble storming off with an incoherent answer and a huff, she was so depressed she couldn't move in time to save her own hide, and she got shot. She barely remembered what happened after that, but she remembered the colors of the rainbow and a pair of magenta eyes staring down on her, not hardly, actually rather caringly. She looked over at Rainbow again, and she saw the same pair of magenta eyes, staring at her the same way. "Yeah," Bubble replied, smiling for the first time in several days, but only for an instant, then she continued with the same irritation as before, "What's it to ya?" Rainbow sighed and said with another of her caring, gentle smiles, "I think I know what Pinkie Pie would do…" Bubble literally had to hit herself, rather hard, with her hoof in the face to keep from becoming perfectly happy and chipper right then and there. Eyes half-shut in boredom, Bubble asked, "What is it?" while smoothing her hair over one eye with her hooves.

"I think Pinkie Pie would say, 'I'd throw her a party, of course!'" said Rainbow, mimicking her best friend's voice all too well. "That's exactly what I was thinking she'd say," thought Bubble. "You know Pinkamena well, don't you, Rainbow Aurora Dash?" she asked aloud. "How do you know my full name?" asked Rainbow. "I have my ways," said Bubble smugly. "Well," said Rainbow, "Yes. I know her well, she's my friend. And as friends, I think we should talk." "Fine," said Bubble, "Let's talk." "You know that song Pinkie sang a little while back?" asked Rainbow, "What did she call it… went like this."

"My name is Pinkie Pie," started Rainbow singing. "Hello!" exclaimed Bubble. She didn't mean that to come out, it just did. "And I am here to say," Rainbow continued, mimicking Pinkie's voice. "How ya doing?" exclaimed Bubble, smiling. "I'm gonna make you smile and I…" sang Rainbow right before Bubble joined in, "Will brighten up your day!" "It doesn't matter now," "What's up?" "If you are sad or blue," "Howdy!" "Because cheering up my friends is just what Pinkie's here to do!"

After they sang the entire song, Bubble bounced out of bed, seemingly unaware of her wound. Her hair was poofy again and she was grinning ear to ear. "So," said Bubble, "How are we going to help Pinkie?" "I have an idea," said Rainbow with a smile, "That just might work."

The next day at lunch, there were 10 ponies that looked just a little out of place. Why? They all had a fluffy hairdo that perfectly mimicked Pinkie Pie's to every detail. Rainbow Dash, Bubble Gum, Sunset Sky, Morning Ice, Sun Rider, Moon Pool, Lasso Loop, Sketchy, Whirlwind and Star Sparkle were there. They were sitting there, eating lunch, not together but quite far apart, sitting with other unicorns, pegasi and earth ponies as they were. Suddenly, as Bubble finished her last sip of juice, she tapped the first few notes on her glass with her spoon of the Smile Song.

"My name is Pinkie Pie," sang Bubble, bouncing down the aisle. "Hello!" exclaimed Sun, popping out from behind Bubble. "And I am here to say," sang Sketchy, prancing down the next aisle over. "How ya doing?" asked Morning cheerfully, appearing on Sketchy's back and jumping off to stand beside her. "I'm gonna make you smile and I," sang Rainbow, flying overhead in circles. "Will brighten up your day!" they all sang together.

"It doesn't matter now," sang Sunset. "What's up?" said Sun, flying straight upwards very quickly. "If you are sad or blue," sang Star, bouncing up to Pinkamena and standing on the table in front of her. "Howdy!" exclaimed Lasso, her slight Western accent only adding to the theme as she jumped out from under the table to stand with Star. "Because cheering up my friends is just what Pinkie's here to do!" they all sang in unison. "Cause I love to make you smile, smile, smile!" sang the pegasi, doing tiny loops overhead in perfect synch. "Yes I do!" exclaimed the unicorns and earth ponies, jumping up on the tables. "It fills my heart with sunshine all the while!" sang Bubble and Rainbow, their perfect imitations of Pinkie paying off. "Yes it does!" exclaimed Whirlwind, proceeding to vault off Rainbow's back into a series of barrel rolls in a giant circle around the ceiling. "And all I really need's a smile, smile, smile," sang everypony at once, forming a giant stacked triangle with Bubble on top, "From these happy friends of mine!"

Jumping off the top of the triangle, Bubble gave the subtle signal for the unicorns to pull translucent but not transparent, black shades over the windows, causing the room to get much darker. "It's true, some days are dark and lonely," sang Bubble, a worried and sad look on her face as she walked, slowly, over to Pinkamena. "And maybe you feel sad," sang Rainbow, coming around the other side and brushing Pinkamena's mane out from in front of her eye, "But Pinkie will be there to show you that it isn't that bad." "There's one thing that makes me happy," said everypony at once, marching down the aisles, "And makes my whole life worthwhile! And that's when I talk to my friends and get them to SMILE!"

Then everypony got up and started singing, pegasi flying through the air and unicorns spelling out, "SMILE" in all different colors of auras in the air, earth ponies bouncing down the aisles and table to table and everypony sang, "Come on everypony, smile, smile, smile, fill my heart up with sunshine, sunshine! All I really need's a smile, smile, smile, from these happy friends of MINE!" And then everypony else kept singing while the 10 ponies who had Pinkie's hairstyle sang, "Yes, a perfect gift for me, is a smile as wide as a mile, to make me happy as can be!"

And at the end of the song, everypony drummed on the table as the 10 friends sang, "Smile, smile, smile, smile, SMILE! COME ON AND SMILE! COME ON AND…" they left out the last word. Pinkamena couldn't resist it anymore. She started glowing pink, her colors lightened and her hair poofed to the fullest poof of poofy poofiness! And that's NOT all, folks, because she put on a grin that looked like it would burst her face and she rocketed through the top of the tent, and when she landed she screamed (Sang? Sing-screamed?) the loudest, "SMILE!" that anypony had ever heard or would ever hear.

"Pinkie!" exclaimed Bubble. "PINKIE!" exclaimed everypony else. "Thanks, everypony," said Rainbow, "We're really grateful." "We includes me, right?" asked Pinkie. "Absolutely," said Rainbow, wrapping a hoof around Pinkie's neck, "Glad to see you're back, Pinkie." "You too, Dashie!" exclaimed Pinkie. "I still hate that nickname…" mumbled Rainbow. "I know!" exclaimed Pinkie gleefully.
