mock toy child

I am looking for a small mock toy that is suitable for children in the age group of 4-7 years. The material of the toy should be plastic so as to be safe for the children and be durable as well. The toy should have features that are engaging for the children in this age group and should not be too complex for them. This mock toy should also have features that provide the children with various forms of entertainment. I want this mock toy to be of appropriate size and weight for these children and be easy to carry and play with.
