|Behind the Scenes|
Marty is a rude and nasty sweet-treat-loving lazy kid who always borrows money from his parents and older sister, and spends most of the time in his messy room.
He hears an ice cream truck passing by his house and immediately runs out of his room to buy ice cream. Outside, he chases the sketchy ice cream truck that has a flavor called Kreamy Cold but fails to catch up with it, as the unseen ice cream man is driving too fast.
The next day, Marty asked his best friend, Ari if he saw the mysterious ice cream truck. Ari tells him that he didn't see or hear the truck, confusing Marty.
A post-man overhears Marty and Ari's conversation about Kreamy Kold, and tells them that when he was a kid he knew a boy named Jimmy Jeffries who got into the truck and the next day he was gone.
Later that night, Marty wakes up hearing "Pop Goes the Weasel" and decides to find out where it's coming from. He walks outside discovering the Kreamy Kold truck leaving him an ice cream cone on his doorstep.
He starts to get even more obsessed with catching the truck after he realizes that he is the only one who can see and hear it.
Marty sells Ari a bike his father gave him, finally earning money to some Kreamy Kold ice cream.
That night, he tricks his parents into letting him go outside and stop the truck using his father's spike strips. After getting in, Marty encounters Jimmy Jeffries who is a now an insane man, frozen on the back of the truck. He tells Marty that the truck has a mind of its own and that he's been waiting 30 years for someone to give his soul to the Kreamy Kold truck so he won't have to do it anymore. Marty tries to escape, but it is too late for him as the doors close by itself. He screams for help as he ends up stuck inside the truck until someone else takes his place. "Until then," says Jeffries, laughing. "It's all you can eat!"
- It's unknown if anyone ever saw him again or that he remains missing while his family and best-friend try looking for him.
- Martin is played by Robert Capron, who is well known as young Curly from The Three Stoogies movie, The voice of Bob in Frankenweenie and is most well known as Rowley Jefferson in the first 3 Diary of a Wimpy Kid movies.
