Never Say Never - S7.E11

Weird Harold's young cousin Robin is staying with his family for a while. He tells the gang she has kidney disease and must undergo dialysis three times a week. Robin's been waiting so long for a kidney donation that she's giving up hope in ever getting one. The gang takes her to a carnival to help get her mind off her predicament. After they take her home, the gang go to the local clinic where they learn about organ donation. Robin goes back to the carnival to have fun rather than spending more time in the hospital. With efforts from the gang and the kidney foundation, a donor kidney is found. The group must act quickly to find Robin so she can be prepared for surgery to get the new kidney. They narrowly make it in the nick of time and with after some post-operation monitoring, Robin will likely be able to live a normal life.
