The next morning, after Mr. Jingles played with a spool, Percy bent down to pet him. "Hey there, Mr. Jingles," Percy said softly and clicked his tongue. He then let the mouse go and retrieve the spool to Del.
Paul and Del were discussing about who will take care of Mr. Jingles after Del's execution until finally, it was decided. Paul was going to be his owner and was determined to keep it a secret. Del, Paul, and Brutal also talked about Mouseville next to Dog University in Tallahassee, Florida, which would've been a perfect place for Mr. Jingles, which would make his owner money.
Del flung the spool across the floor and the mouse started to chase it until a familiar guard, carrying food, accidentally stepped on the victim.
Mortified by what Percy had done, Del ran out of his cell and screamed, "NOOOOO! YOU KILLED HIM! NO!" Seeing this, Brutal and Paul restrained him.
Wild Bill, Harry, and Dean had seen the disturbance.
Percy lifted up his foot to see a dead mouse with blood coming from his head. Paul marched over to him. "I didn't mean it," Percy said remorsefully, "It was an accident. I was carrying food for the little guy." He looked at Del, who was alone in his cell in shame. "I'm sorry," he apologized to him.
"Okay, but next time, watch where you're stepping and break off tiny pieces for him," Paul warned.
Percy nodded, taking his warning very seriously.
Suddenly, a familiar enormous hand stuck out of a cell and John ordered the guards, "Give him to me. Give him to me, there might still be time."
Paul picked up the dead mouse and gave him to John.
"Please, John, help him!" Del cried out desperately to John sadly, "Please, John, help him!"
Percy nodded in agreement, also with a lump in his throat. He was ashamed of killing Mr. Jingles.
John cupped the mouse into his hands and breathed into him. Just then, a bright light shined through his hands. Everyone stared in amazement, seeing Mr. Jingles revived. When John was done, the little mouse scurried out of John's cell and back to Del, who cried tears of joy. Percy, too, was starting to feel better.
Dean turned to John and asked, "What'd you do?"
"I helped Del's mouse," John replied, "He's a circus mouse – gonna live in a mouse city down in…" John struggled to figure out the right word.
"Florida?" Brutal finished for him.
John nodded and continued, "Boss Percy sad. He meant no harm when he stepped on Del's mouse. I took it back, though."
"Merci," Del whispered to John and he played with Mr. Jingles.
"Del, I'm really sorry I stepped on him," Percy Wetmore apologized.
"That's okay," Del assured him, "I forgive you and Mr. Jingles forgives you, too." Then he and Percy hugged. "He likes you," Del said, referring to Mr. Jingles.
