Christmas gifts for 3 yr old boys?

​Okay mamas. Who has any great ideas for gifts for a 3 yr old boy. My son has so many toys already. We would really like to get him something he can be active with. He loves monster trucks & race cars.

I'm currently a stay at home mom with my 2 yr old son. We are also trying to have another baby. =) We just bought our first house in the country and are loving it. Family is one of the most important things in my life.
