The coloured tubes are hollow and flexible, creating a soft, but not squishy, teething toy. The tubes are also thin enough for even very young babies to easily grip, grab, and move the toy about. Being shaped like a sphere and thus having no right way up, the baby can turn the toy around with one or both hands, allowing for a more carefree experience. Thin tubes also allow for babies to easily grip the toy with both hands, encouraging two-handed play, a developmental milestone for babies. The cube has a quiet rattle inside, which could help a child learn basic cause-and-effect, connecting the sound of the rattle to the timing of the baby's movements. Additionally, the toys light weight means the baby is not hurt or greatly shocked when it eventually hits the toy against its own face.
