Mr. Halloweenster is the kids Halloween hero. He's always there to help with costumes, pumpkin carving and everything else that makes Halloween fun. But this time, while Mr. Halloweenster is helping the kids, there's something tricky happening at the JunkVittles Candy factory. Mr. MeanyPants and Dr. JunkVittles are making candy that will make the kids forget about their costumes and the Halloween parade. Only Mr. Halloweenster can save the day!
Mr. Halloweenster loves Halloween, but what he cares about most is that all kids have fun on Halloween. Mr. Halloweenster's costume swap shop is filled with costumes and decorations that he saves from being thrown away, because he knows there are lots of kids who still want them.
Mr. Halloweenster is a "big kid" in disguise whose real name is Stanley Stickler. Stanley got teased a lot when he was young because most of the other kids thought that the way he looked and talked was funny. Stanley spent a lot of time at the library, where he especially liked books about animals. His favorite animal was the platypus, and he imagined that he and a platypus would be friends, because it was also considered funny looking by most people. When he was six years old, Stanley actually did become friends with a platypus named Fran.
Mr. MeanyPants has been mean since he was a little kid. His real name is Michael Meahan Pence, but nobody knows why he is so mean. Mr. Meanypants' favorite thing to do is to stop other people from having fun, especially kids, which is why he wants to ruin Halloween and why he really doesn't like Mr. Halloweentster.
Fran has been a friend of Mr. Halloweenster's since he was six years old, when his name was Stanley Stickler. When they first became friends, Stanley would tell Fran about his two friends Demetrious and Shmutzy. Fran also listened to Stanley talk about the kids who weren't nice and teased him.
Fran would tell Stanley stories about many different animals. Some were friends who had fun together and helped each other, but there were also mean animals that tried to ruin the others' fun. Hearing these stories helped Stanley understand why some kids were nice and others weren't, and taught him to not be upset about getting teased by other kids. It was through these stories, that Fran helped Stanley become Mr. Halloweenster, which is when he stopped being afraid of Michael Meahan Pence, the meanest of all the kids who teased him, who Stanley called Mr. MeanyPants.
Dr. JunkVittles likes to make things that trick people. Mr. MeanyPants and Dr. JunkVittles worked together to start the JunkVittles Candy Company so that they could trick kids by getting them to eat Tricky Treats, and ruin their Halloween fun by turning them into candy kookies.
