$15.00 Fisher-Price Big Action Boulder Blast Quarry-It’s so easy for little ones to make big action happen at the Big Action construction sites. At the Boulder Blast Quarry kids can scoop and load boulders into the bulldozer. Then drive on over to the EZ Guide Ramp—it lines the RC vehicles right up to the main site (sold separately). Dump boulders into the quarry site and 1…2…3…KABOOM! Kids can push the dynamite blaster for real exploding action! Reload and re-set at the push of a button. Works with all of the Big Action playsets and RC vehicles too!
