Help! Gift Ideas for 3 1/2 yr old boy

I am at a loss on what to get him this year. He LOVES trains, but I don't want to get him anymore because he has so many. I have to get him one bc that's what he is asking Santa for. I'm getting him a new bike, but have very few ideas for everyone that's asking me. We are going to redo his room before I have the baby with a train theme so I'm looking for stuff along those lines, but what gifts are you getting your 3 1/2 year old boy?

Ds will be getting a Narnia castle, some early learning games (Chutes and Ladders, CandyLand, etc..), some Transformers, dinosaurs, art supplies, a ride on car (but that's actually being purchased with bday return money), a walking/roaring dinosaur, and probably a bunch of other junk he really doesn't need.
