Lionel "Where The Wild Things Are" Boxcar
So...one of the traditions here is to try to find a train car that 'means's something to each of the boys. This one, is aimed at a special guy and will hopefully appeal to him (and his parents!) and build on his collection of cars. At some point, he's going to need a locomotive, too!
But, this car is an 'aquarium car', so the inside is illuminated and there's a series of cells that move along as the car moves, so this really comes to life. Should be fun to see it around the track.
