Help me think of a present for a school buddy!

[twinky]

DS has a boy aged 11 who has been his school buddy since he started in August. He's been really lovely with DS and I want to get him a little something for Christmas to say thankyou. However, I don't know the first thing about what he likes and he has multiple food allergies so chocolate and sweeties are out. Do you have any suggestions? I don't have children old enough to know what's popular with boys of this age group.

Lego? can add to existing sets he may have.

Take them both to the cinema as a treat (on their own - ish of course)?

Top trumps? Hi lighter pens? Diary?

Mine always exchanged sweeties with buddies, so just something very small I think.
