Lego Ninjagos, Spiderman, Spy gear

I got my son a talking microscope for $30. Bug parts included.

I have 5 and 7 year old boys and their entire Christmas list is Lego.

My son's entire list has to do with Beyblades and Pokemon in all of their various incarnations.

Legos are good. So is Superhero stuff. We're getting DS a couple of Superhero figures with the corresponding origin story books (Amazon and Barnes and Noble have them).

Lego Ninjago, Star Ward, Angry Birds, Batman / Superhero stuff are what my six year old wants.

^^^ not a complicated one though

Lego Hero Factory figure!

Remote control air swimming shark.

My six year old son's Christmas list has 2 items -- a DS and a harpoon. Don't think either of those are what you're looking for . But some other things he loves are lego kits (especially Ninjago), a battery-powered lantern, sports equipment -- soccer balls, footballs, basketballs (also give a hand held air pump so they can keep them inflated), magic trick set, UNO, checkers, battleship game, or hex bugs.

Legos are good. Science kits (I'm always recommending science kits on here!) headlamp. Books. I found this transfer paper online...you put an object on it (like a leaf) and put it in the sun. Take off the leaf and the shadow is there. Looked cool. That was on yo-yo (sister site to diapers.com)

OP here. Thanks!

Legos. Ninjago and Star Wars are the most popular right now for that age group.

I am participating in a toys for tots program and have to buy a present for a 6 year old boy. I have a 3 year old girl so I have no idea what a 6 year old boy would like. Can anyone help me with some ideas? TIA
