Review for LEGO set 79120 T-Rawket Sky Strike from The Brick Castle

“The set contains the T-Rawket, the Kraang Ship and 4 excellent minifigures - Donatello, Michelangelo, Mutated Dr. O’Neil and The Kraang with their weapons and accessories. The play value is excellent and it really does give children a whole scene to recreate the stories... More from the DVD/show and to use their own imagination.”
