Last time it was the Smurfs, then Alvin and the Chipmunks (and the Chippettes), then came the Puss in Boots series, and also this pinball-like thingy.
McDonald's always come up with something that attract little kids, which I have to admit, my daughter is hooked. Her faves are chicken nuggets (except when it's spicy), french fries, iced Milo, and vanilla ice cream. Sometimes, when we go out, and it's time for a meal, we would order "to-go" for her and would bring the meal to our restaurant or fastfood chain of choice. (Of course, that's when we opt to eat at another "makan" place).
And back to the Happy Meal, lately she enjoyed the collection very much because her favorite Hello Kitty was the feature! She even brought one to our last trip to the Philippines.
