It's Halloween and time for the Monster Machines to truck or treat! Crusher doesn't have a costume picked out so he tries on all sorts of outfits with Pickle's help! Which one should he choose?
Synopsis[]
The short starts with a truck dressed as a princess giving candy to another truck dressed as a pirate. All the monster machines were admiring all their costumes. As Crusher drives past, questioning himself why are pumpkins and costumes. A yellow truck in a ninja costume drives past wishing Truck-or-Treat, this makes Crusher realise that it was Hallowenn and he did not have a costume.
Pickle walks up to him, asking him what's wrong. After Crusher tells his problem, Pickle giggles and tells him that he also doesn't have one and brings him to a garage. Pickle picks up a radio and cues music saying "Let's get to work!". Pickle finds a chicken costume for Crusher, but he didn't like it. Pickle gives Crusher another costume, a cowboy but he didn't like that Pickle accidentally lassoed his tire.Pickle gives Crusher a clown wig, which he disagrees on. Followed by, a flower hat, a monkey costume, an astronut, a mustache, a train, ballet tires, a chef's hat and a lion. He ended up choosing a lion, while Pickle wears a flower costume.
Crusher and Pickle go for Truck-or-Treating as they went door to door for candy. While they were doing that, they met up with Blaze and AJ who was dressed up as a superhero and a ninja respectively and they invited them to follow them. They also get more candy when a truck breaks open a pinata. The short ends with trucks dancing along the streets and wishes a happy halloween to the viewers.
