You need to move "toys: []" in your person class to the initialize
method:
var Person = Class.create({
initialize: function(name) {
this.name = name;
this.toys = [];
},
speak: function() {
var string = "My name is " + this.name + ". My toys
are: ";
$A(this.toys).each(function (toy) {
string += toy.name + ",";
}.bind(this));
alert(string);
},
appendToys: function(items) {
$A(items).each(function (item) {
this.toys.push(new Toy(item));
}.bind(this));
}
});
