My ds is totally into pull toys, he has a snail that makes a little slithery noise as it follows him. He loves it, it's like playing chase by himself. He also like a little ride on firetruck, he just figured out how to make it go forward today, but he's been riding it backwards, getting off, pushing it across the floo so he can go across the room backwards again. However, he does try to stand on the seat every once in a while. And all of a sudden he's in to Matchbox cars, going vroom vroom across the carpet crawling with it. Hope that helps.
