"Heir to the Throne" is the twentieth episode of the first season in ATF's Episodes. It is the twentieth episode overall.
The episode begins with Princess Bubblegum and Silver Prince in the library talking. Princess Bubblegum then screams in pain and falls out of her chair and on her back on the floor. Silver Prince picked her back up and put her back in the chair and told her that she is going to get a doctor. Princess Bubblegum said "I...ts tim....e!!" Silver Prince ran to Doctor Ice Cream in the royal corridor. He grabbed her arm and pulled her toward the royal library. He told that Princess Bubblegum is going to have her baby. Doctor Ice Cream grabbed Nurse Poundcake and a stretcher and ran to the library. When they got there Doctor Ice Cream and Silver Prince lifted her into the stretcher. Doctor Ice Cream and Nurse Poundcake pushed her into the emergency room. In about ten minutes, Finn, Jake, Flame Princess, Ice King, Marceline, and all the Candy People were outside of the emergency room.
After about 3 hours, Silver Prince, came out. Finn asked if she was ok. Silver Price said she is ok. Then Nurse Poundcake opened the door and told Silver Prince to come back in. Then he ran back in and closed the hospital door. Ice King was crying and said "I can't believe my number 1 is having a child with someone else!" Just then, Silver Prince came out. He walked up to Ice King, and punched him and said "You! Get out of here if your are going to keep on saying that about my wife. Or you can stay here and wait quietly!" With that he walked back in. Finn said, "Go Silver Prince!" Flame Princess started to laugh.
Then after about 5 hours, Princess Bubblegum and Silver Prince came out, holding their baby. Everyone started to cheer. Finn asked what her name was. Princess Bubblegum replied "Gum. Princess Bonnible Gum. Duchess of the Candy Kingdom." Silver Prince and Princess Bubblegum kissed. They walked up to the Master Bedroom and closed the door. Then it shows Princess Bubblegum in a rocking chair singing a lullaby with Silver Prince by her side. Then the episode ended.
