MOONIE is the only humming toy with the highest quality natural pink noise, not computer generated. Due to the fact that the sound of the heartbeat is a real recording from inside the mother’s belly, the baby can calm down and feel safe with the already well-known sound. The sound of sea waves was recorded by the Baltic Sea, and the sounds of a forest stream in Tarach. MOONIE is the only humming toy with a built-in lamp, which helps with the night care of the child, and helps the older one overcome the fear of the dark. MOONIE is the only humming toy that is charged via a USB cable (included with the toy) and does not require the purchase of additional batteries or rechargeable batteries. Teddy bears from the MOONIE ORGANIC collection are the only humming toys made of organic cotton with a GOTS certificate.
