About LEGO Knuckles vs. Dr. Eggman Egg Crusher Mech

350 pieces bring together the formidable Egg Crusher Mech and iconic Sonic characters in this action-packed battle set. The centrepiece is Dr. Eggman's buildable mech, featuring a 6-stud rotating launcher, giant spinning claw and fully articulated limbs for dynamic posing during play. The set also includes a hoverboard for aerial manoeuvres and detailed minifigures of both Knuckles and Dr. Eggman.

Battle Features

The mech stands over 15 cm tall when built, creating an imposing presence on the battlefield. A separate catapult with terrain base launches boulders using a simple lever mechanism, measuring 4 cm high, 6 cm wide and 7 cm deep. The catapult comes with two boulder projectiles for launching attacks against the mech.

The set is designed for builders aged 8 and up, offering multiple play scenarios through the combination of the posable mech, projectile catapult and character accessories. The articulated design allows for various action poses while the rotating launcher and spinning claw provide interactive mechanical functions that enhance the play experience.
