Tying a blanket around his shoulders as a cape and "being Batman" =)
Star Wars: Journey Through Space - we like this one b/c it explores a lot of the planets from Star Wars. =)
Charlie & Lola - books and videos, but especially the videos
The Lego Star Wars planet series sets - we just built the TIE Interceptor & Death Star kit. He flies the little spaceship around and makes goofy boy noises. Pretty cute. =)
The Twilight Turtle - nightlight that puts stars on the ceiling. He's loved this since he was a baby.
