Hot Wheels: Monster Trucks - Season 4

Bigfoot tells the other trucks a spooky campfire story when Bone Shaker interrupts, sending everyone on a wild chase after him and the Phantom Trophy. Traversing a haunted forest, a scary swamp, and a crystal-filled cave, the trucks must catch Bone Shaker, teaming up to take the trophy back.

Rhinomite brings out a new robot version of himself: the Rhinobot 9000, but when the controller breaks, the robot goes haywire, forcing the trucks to try to stop it from destroying the island.

After a volcano spontaneously erupts, the trucks race to ring the bell at the top of a fire tower to warn everyone. As they careen through the course, the trucks find themselves in the line of a raging stream of lava and it's up to Bigfoot to bring the crush and save the day.

After mistakenly thinking the other trucks forgot his birthday, Bigfoot wishes for friends who really understand what his birthday means to him -- and gets his wish in the form of three new Bigfoots, all different versions of himself. While things start out friendly, they take a dark turn when "Fifty" (50th Anniversary Bigfoot) decides he wants to be the only Bigfoot on the island.

Bigfoot faces off against Fifty, Goldie, and Rookie-B to decide who will be named the one and only Bigfoot. The other trucks act as coaches, commentators and referees for the event. Bigfoot is going to have to dig down deep if he wants to beat his other (sometimes bigger) halves.

A beef between Tiger Shark and Mega-Wrex turns into a full-island battle between two teams. Team Shark and Team Dino. When the stakes rise, the trucks must decide which comes first: winning the championship or their friendship.
