The Hot Wheels City Ultimate Hauler converts from a 20+ car transporter into an interactive T-Rex with animated features. When rolled forward, the hauler simulates a T-Rex devouring 1:64 scale vehicles in its path, while also functioning as storage for over 20 cars. Pulling the tail activates the transformation, revealing a T-Rex with stomping motion, glowing red eyes, and sound effects including chomps, burps, and farts. The T-Rex features a two-lane race track on its back, where included Hot Wheels cars can compete. The winning car continues forward, while the second-place car exits through a rear mechanism. Kids can also launch cars from the T-Rex’s mouth, creating the illusion of the dinosaur spitting them out. The set includes two 1:64 scale Hot Wheels cars and is designed for ages 4 and up.
