Engage your little one's curiosity and support their development with this 24-piece block and ball tower bundle from Infantino. The Bop & Drop Ball Tower introduces babies 12 months and up to STEAM concepts through colorful cause and effect play. Watch your baby delight as they use the included kid-friendly hammer to bop the 4 matching balls through the tower's two slides and two peek-a-boo tunnels. The see-through tower lets them investigate where the balls travel, building hand-eye coordination, fine motor skills, and problem-solving abilities along the way. Once the balls have all dropped through the tower, the 24-piece Press & Stay Sensory Block set lets even the youngest builders easily stack, attach, and pull apart the blocks thanks to their unique interlocking pattern. The high-contrast colors and interesting textures encourage open-ended building play and imagination in babies 6 months and up, with no alignment frustration. With one toy focused on STEAM skills and the other focused on creativity, this Infantino bundle covers all the developmental bases. Let your little one build up their skills while they build up some blocks and knock down some balls!
