One night, which was eventually going to turn out to be an eventful night for our main characters real soon, the three Diamonds of Homeworld - White, Yellow, and Blue - were having another one of their visits to Earth.
Tonight, they were visiting the house of their good friends, the Kavinskys - with Yellow altering their giant sizes to human size, of course.
"Ah, we can always depend on the Kavinskys to count on us to sing a lullaby for them!" said White to Yellow and Blue as they were all climbing up the stairs to their bedroom door. But when they got there, they heard an enthusiastic female's voice from inside.
"Oh boy, do I love this Serta mattress!"
White's ears perked up.
So did Yellow and Blue's.
"Serta"?
It can't be...
White took a peek through the door, which was open just a crack.
It could be, and it was.
There, before the eyes of White Diamond, was a small Serta tag on the Kavinsky couple's mattress.
"Oh, no!" said White, rather upset. "They got a Serta, too?!"
The Diamonds were dejected, now that they can't sing a lullaby for their human friends... especially since this wasn't the first time a Serta mattress had upstaged them.
"Now I know how the sheep feel," said Yellow.
The Diamonds turned away from the bedroom door to leave.
...but then White heard something.
The excited voice of the female sounded young, and full of bubbly, carefree fun...
Just like...
"Wait a minute," said White, now becoming angry. "I know that voice!"
White marched back to the bedroom door, and pushed it wide open.
Just as the Diamonds had feared.
The Kavinskys - especially Mrs. Kavinsky - weren't anywhere on top of the bed.
They were only standing by, watching someone else having ecstatic fun wriggling on top of the Serta mattress, taking in the softness of it.
It was Spinel.
The pink gem was having the time of her life feeling the best mattress she had ever felt... until she noticed her angry Diamond friends standing in the doorway. Spinel was so shocked, she looked as if she was a deer in the headlights.
White Diamond's eyes narrowed at Spinel.
"Traitor..." she hissed.
Spinel chuckled nervously.
Before Spinel was able to explain herself, White grabbed Spinel, and threw her at the window. Spinel smashed through it, before she landed in the bushes outside.
After she landed, she could hear White's sharp voice shouting, "There! Are you comfortable now?!"
Spinel groaned.
This turned out to be a heck of a night for both her, and the Diamonds.
