This Skip Hop Stack & Crawl Crawling Toy is an interactive crab-shaped crawler and developmental activity toy that encourages early motor skills with lights, sound effects, music and lively movement. With four progressive stages—rattle and teether, sorting and stacking, plus beginner and advanced crawling modes—this toy adapts as baby grows to support hand-eye coordination, grasping and crawling. This interactive crab peeks from under a movable shell, rolls in a circle for beginning crawlers and shifts to more unpredictable paths for chasing play that builds gross motor confidence. Constructed from durable ABS and PP with soft EVA details, this stacking and sensory toy provides safe teething textures and easy-to-clean surfaces for everyday play. Compact design and bright, friendly colors suit nursery and playroom spaces, making this an ideal first crawler and stacking companion.
