The document summarizes observations from a user trial of a moving toy with kindergarten children ages 3-4. The children were able to identify the toy animals and played with the toys in creative ways, such as pretending the spring was a guitar. However, some children pulled the springs too hard in a way that could hurt others. Based on the children's engagement and requests to buy the toys, the trial suggests the toys were generally a success, but that safety instructions may need to be provided.
