As you may know Lego stores have a free monthly Lego Mini Build where children can come along to store and build a mini model each month and get to take it home for free afterwards.
It's usually on the first Thursday of the month in UK stores, and August's mini build is a cute Kangaroo, complete with a Joey in the pouch.
You don't need to book for this event, just turn up to your local Lego Store between 4pm and 6pm on Thursday 6th August and you will get to build and keep your model.
This event is only open to children aged 6 to 14 only (sorry grown ups), and it's one model per person while stocks last.
Not bad for a freebie, and there's one every month. You can find details of this and the other current Lego promotions here on the Lego Stores website.
