One day, Chase, Marshall, Zuma, Rocky, Skye, and Rubble had a mischievous idea. They decided to play a prank on Walker, Ryder's older brother.

Walker was always there for Ryder and the pups. So when Ryder was out of town, Walker was put in charge of the PAW Patrol.

The pups respected Walker and saw this prank as a fun way to bond with him. They spent the whole day planning and preparing.

The prank was set. Chase was extra careful with the details. It was a harmless prank involving a bucket of water and a few harmless paint balloons.

As Walker entered the room, the bucket tipped, spilling water everywhere. Simultaneously the pups sprang out from their hiding spots, throwing paint balloons.

Walker, surprised and momentarily blinded by the paint, slipped on the water. He fell hard, making a thud that echoed through the lookout.

Things had not gone as planned. The pups raced over to Walker, who grimaced in pain. Marshall quickly examined him, fearing something was wrong.

Swiftly, the pups called for help. The ambulance arrived, taking away Walker on a stretcher. The pups, once filled with excitement, now felt a wave of guilt.

The lookout was eerily quiet after Walker was taken away. The pups sat in silence, regretting their decision to prank Walker.

They decided to investigate what went wrong. Rocky took the lead, inspecting the area where Walker had fallen.

"The floor was slippery than we thought," Rocky concluded. "And the balloons blocked his sight more than we expected."

"We should never have carried out the prank," Chase said. "We forgot to factor in safety."

Feeling responsible, the pups decided to make amends. They were determined to apologize to Walker once he got back from the hospital.

In the meantime, they cleaned up the mess they had made. "We should be more thoughtful in the future," Marshall said as they worked.

The next day, they received news that Walker had a sprained ankle but would be fine. The pups were relieved but they knew they had to apologize.

When Walker returned home, the pups greeted him with lowered heads. They were met with Walker's understanding smile.

Each pup, one by one, apologized to Walker. They promised not to prank others without considering the consequences. Walker accepted their apologies.

"It's okay," Walker said. "I know you didn't mean to hurt me. But remember, pranks should always be safe and fun for everyone."

The pups nodded in understanding. From that day on, the pups were more responsible and made sure their pranks were safe.

And Walker? He was just as understanding and forgiving as ever. Even though he was pranked, he remained a great role model for the pups.
