This set also stimulates imaginations as toddlers invent creative stories by pretending to climb into their toy truck cab to head off for a new adventure. For Fun Family Playtimes This educational toy is designed to encourage toddlers to engage with the alphabet, wherever they are on their learning journey. It includes a stereo element to encourage fun ABC sing-alongs with parents and toddlers.
