Birthday present for 4yo boy?

[Glamourcide]

Wow, thanks so much ladies You've given me some great ideas!! I was sooo stuck, lol now with those suggestions I feel like an idiot for worrying hahaha, I'm so used to buying girlie things for DD I really just have no idea what is out there for boys!!

Now all that's left to do is convince DH to come shopping with me when he finishes work hahaha, or maybe I can con him into minding DD so I can shop in peace

Thankyou so much, girls I'm so grateful

Edit: So, looks like my gift was a hit lol... Big W had barely any Ben 10 stuff (I was so disappointed!!) so I went with a Ninja Turtles figurine thingee... I figured I LOVED TMNT when I was a kid (mum was even telling little Z's family today at the party that I couldn't be budged from the TV during it, and I still have old episodes on VHS tapes hahaha), so I got that and then hoped 4-yo boys are into spiders, rather than scared of them, because I bought wrapping paper with cartoon-looing spiders all over it hahahaa...
Anyway we got to the party, I gave him his present, he ripped it open and ran around the room screaming, 'MUM! MUM! IT'S A RAPHAEL ONE, YAAAAAYYYYYYY!!!' and begged to be allowed to open the box and play with it then and there hahahah - he even forgot that they were in the middle of setting up his new Wii!!
So... I'm happy lol.
But thanks again so much for the tips, ladies Now I will know what kind of stuff kids that age like if/when I ever get an invite to another 4th birthday party lol
