Sunny Sanders also known as America's Sweetheart was a teenage girl who went to school with her boyfriend Teddy and their friends Barbara and Richard "Ritchy" Richardson. She lived with her parents Sam and Jeanette Sanders.

In the story ''Wolves and Whistles'', Sunny wants Teddy to take her to a moonlight sail party, but he doesn't have enough money for the ticket. Sunny decides they can sell the old papers in her basement, but it rains and the junk man's assistant pays for the wet papers by weight. Earlier, Sunny's mother discovered wolf whistles and is feeling suspicious of boys. She overhears the junk many accusing Teddy of being a thief over the wet papers, and forbids Sunny to see him. At the advice of Richy, Teddy tries to get Sunny's attention with a wolf whistle, but attracts the attention of Ginny instead, leading to a fight between the girls. Richy explains that Teddy was practicing a call for Sunny later on, which means that he actually has to do it to prove the story to Ginny. Ginny tries to set it up so Teddy is heard by Sunny's father. This works, but Sunny's mother is also nearby and thinks her husband was whistling after girls. She tells Sunny she can go because it's Mr. Sanders she has to look out for.

Then in ''Evening Gown Blues'', Sunny wants a new $20 dress for the prom. Her mother says that if she cleans the attic, she'll give her $5 and she can sell whatever she finds. When Teddy comes by she gets him to help her move a large desk, and they find a letter with a rare Civil War-era stamp. They look up the stamp and end up writing to Mr. Dunby of Dunby and Smellin stamp collectors. Dunby writes back valuing the stamp at $200, but Smellin hears and dashes to offer them $20 first. Teddy thinks that's low, but Sunny just wants the dress. Fortunately Dunby's letter, followed shortly by Dunby himelf, arrives and stops Smellin as he's running away. Dunby buys the stamp for $200, and we see Sunny and Teddy happy at the prom, where Sunny says she was surprised that her mother bought her the dress after Sunny gave the $200 to a children's clinic she heard about on the radio.

In ''Love in Boom'' , Sunny and Teddy are trying to get to the roller-skating rink. Teddy is careless and splashes through a puddle, drenching Penrod, a boy Sunny's mother thinks is much better than Teddy. Penrod swears Sunny's mother will hear of Teddy's carelessness. Teddy has more trouble as his car gets a flat and then runs out of gas. By this point Sunny's mad over the delay and the fact that Teddy has oil all over his suit. By this point, Sunny's father, smoking a cigar Penrod gave him, shows up to haul Sunny off based on Penrod's latest allegations against Teddy. Through a series of mishaps, though, there ends up being a gas explosion that buries him under some junk, causing Sunny and Teddy to briefly think him dead. It turns out that the cigar Penrod gave him was an exploding trick cigar, and caused the larger explosion. Mr. Sanders is not amused and throws Penrod out, clearing the way for Teddy to keep dating Sunny.
