Propel Magic Stunt Marbles into the T-Rex's jaws and see him chomp them down to kick off exciting marble action. Create three dino-mite builds using the easy-to-follow leveled guide by connecting the 109 color-coded pieces including a dino-snack launcher, a magic spin elevator and exciting tracks! Create your own courses to explore STEAM (Science, Technology, Engineering, Art and Math) skills. When the gravity-fed course is complete, drop five colorful marbles into the course to watch them speed around the tracks. Launch five metal-core Magic Stunt Marbles to feed the T-Rex, then see them spiral up the magic-spin elevator or glide across a magnetic zipline! Combine with other Marble Rush sets (each sold separately) to create an extreme playset. Find more build ideas at the VTech Kids website. Intended for ages 4+ years.
