In the bustling city of Townsville, the evil Mojo Jojo had managed to capture the Powerpuff Girls. He had used a shrink ray to miniaturize them and had trapped them inside a glass jar.

Mojo Jojo took his captives to his evil lair, planning to get rid of them once and for all. But he decided to take a break and went to relax in his bathroom, leaving the jar unattended.

Inside the jar, the girls managed to escape. They quickly hatched a plan to recapture Mojo Jojo. They decided to split up and explore the lair for any tools or weapons that could help them.

Blossom found herself in Mojo Jojo's bedroom. She spotted the shrink ray, the very device that had miniaturized them. But it was not working, and she had to find a way to fix it.

Meanwhile, Bubbles and Buttercup had found their way into the bathroom. They saw Mojo Jojo relaxing in a bubble bath, his dirty feet sticking out of the bubbles. They knew they had to distract him.

Bubbles decided to play the role of a spa attendant. She began to pamper Mojo Jojo's feet, her tiny hands scrubbing his giant toes. Buttercup stood by, ready to attack if necessary.

Mojo Jojo, surprised at first, eventually accepted the attention. He was completely unaware of the girls' true intentions. Meanwhile, Blossom was trying hard to fix the shrink ray.

Suddenly, Mojo Jojo realized that the foot massage was a bit too good to be a coincidence. He looked down and saw the Powerpuff Girls. Enraged, he tried to grab them, starting a little scuffle.

Bubbles and Buttercup fought with all their might, dodging Mojo Jojo's massive hands. At the same time, Blossom finally got the shrink ray working. She hurriedly ran to the bathroom, ready to save her sisters.

Just as Mojo Jojo was about to capture Bubbles and Buttercup, Blossom burst into the bathroom. She aimed the shrink ray at Mojo Jojo and fired, shrinking him down to the size of a regular monkey.

The tables had turned. Mojo Jojo was now tiny and powerless. The girls then used the shrink ray on themselves, returning to their normal size. They had defeated Mojo Jojo, proving once again that evil never triumphs.

The Powerpuff Girls returned to Townsville, the city they always protected. Mojo Jojo, meanwhile, was left in his tiny state, trapped in his own lair. The girls had saved the day yet again, demonstrating their bravery and teamwork.

The city of Townsville rejoiced, knowing that their beloved Powerpuff Girls were safe and sound. Mojo Jojo's evil plans had been foiled once again, thanks to the girls' quick thinking and determination.

As for Mojo Jojo, he learned a valuable lesson that day. No matter how cunning and devious he may be, the Powerpuff Girls will always be there to stop him and protect their city.

The Powerpuff Girls, having returned to their normal size, flew back home. They knew they would always be ready to face any challenge, no matter how big or small. After all, they were Townsville's greatest heroes.
