Other than toy vehicles, my boy enjoys the miniature toys of animal too. Sometimes, he sets a battle between a tiger and a lion or a leopard and an elephant. Sometimes, he takes few of them to nap together or even take shower with him. Although my boy hasn't met any of these animals in real (in the Zoo), he learns most of them from picture books.
Still remembered that he would see a tiger's picture and say it's a lion. Haha.. but now he's playing the toy animal everyday, it's impossible he could name them wrongly again.
