My daughter spends hours on this play mat. I only use the sound "nature" that is perfect for her (and for us !!!) but there are also songs. Very well designed, the colors are bright and toys are charming and entertaining. Every little character has a particular interest and it is possible to place them wherever you want (either in the air or on the ground).
Negative points: The carpet is not thick enough (problem solved by placing it on another mat or a blanket folded in half). Once mounted the ark is not removable ...
