- Color recognition - Each egg features two different shades from the same color family
- Auditory discovery - Each egg makes a different noise! The green chirping egg sounds like a baby chick and is a fan favorite.
- Fine motor development -Sound explorers will notice the light blue egg doesn't make sounds when shaken. They'll work fine motor skills as they figure out how to twist the egg and make a clicking noise.
The blue twisting egg features a natural (unpainted) wooden dowel. This is not a defect, but an intentional part of the design.
