Five areas divide the floor: sea, forest, town, station, and one for babies alone. The sea holds a ball pool of roughly 40,000 balls with a ten-metre ship afloat in it, plus a padded trampoline. The forest is laid with artificial grass and stocked with board games and educational toys. In the town, children play shopkeeper at a doughnut shop, a sushi counter and a pizza place. The station carries every current Tomica car and Plarail train.
