The two toys have suction cups on the bottom, allowing them to stick to tables and other surfaces. They make sounds when you shake them, and have different textures, making them fun to play with. Even when they were little and their hands weren't very strong, they would concentrate on playing with them. The five-sided toy shows signs of use. It has lights, sounds, and various stimulating features like pulling and turning parts. They would fight over it to play with it. The cloth book has different textures on each page. If there's anything unclear, please feel free to ask in the comments, even if it's just a question.
