Once, there was a girl named Madison, who went by Sparky. She had an imaginary friend named Kat. Sparky hadn't created Kat, though, she found her.

One day, Kat heard very bad news, Sparky was moving- which meant they had to get rid of Kat! After dinner, Sparky and Kat were watching television, when a commercial came on. It was about a place called "Foster's Home for Imaginary Friends", where you could bring your imaginary friend, and they would live there. Sparky looked relieved that Kat wouldn't be a gonner. "Please don't!" Kat thought. She didn't want to go. Sparky made Kat pack her bags, then she listened to their favorite radio station, and one of their favorite songs was on, Gives You Hell by All American Rejects,
"Now you'll never see,
what you've done to me,
you can take back your memories,
they're no good to me,
and here's all your lies,
you can look me in the eyes,
with the sad, sad look,
that you wear so well..."

Kat went to bed feeling very sad that night. The next morning was the big day. "Nooo!" Kat whined. "Now way, Kat! You're gettin' your furry heinie in, there even if I have to drag you!" Sparky replied. Sparky's mother rang the doorbell, and a pretty girl with red hair answered. "Hi, I'm Frankie! Welcome to Foster's Home for Imaginary Friends! Come in!" she said. "I'm here because my we're moving, and my daughter can't keep her imaginary friend, Kat." Sparky's mom explained. She went to Mr. Herriman's office to fill out some paperwork.

Just then, a boy came running around the corner, along with a blue imaginary friend. They bumped into Kat and Sparky. "Oh, sorry!" said the boy, "I'm Mac." "I'm Madison, but you can call me Sparky." She replied. "Woah, dude! Sorry for standing in that spo-"
"Who the heck are YOU?" said the blue friend.
"Excuse me? Um, I'm Kat, and you don't have to talk to me like that!"
"Oh yeah? Well-"
"Bloo! Stop it!" Mac said, "Kat, don't mind Bloo, he's just being a-"
"DOOKIE!" Kat yelled happily.

They were becoming great friends, and Kat and Bloo were, too! Until Sparky had to leave- for good. "Oh, I love you, Sparky!" Kat sobbed. Mac and Bloo invited Kat to play with them for a bit. They were building rockets. Kat was about to launch one.
"Kat! Move!" Mac said.
"Huh?" Kat yelled.
"KAT, JUST GET OUT OF THE-" Bloo yelled. BOOM! The rocket blasted into the air, with Kat attached by her tail. The rocket exploded. "We only knew her for three hours." Bloo said sadly. Suddenly, Kat crashed in front if them, covered in smoke. "LET'S DO IT AGAIN!" Kat yelled. They started laughing. It was then that Kat realized she liked Bloo. She LOVED him. She blushed.
