Are there any non choc advent calendars out there for 12 year old boys?

[Happybell]

However open to ideas to choc/sweet ones that are a bit different :)

Dogs Trust have a picture one

I'm getting dh a pork scratching one but doubt that'll appeal to a 12yo!

Oh notsure please share where you've found a pork scratching advent calendar dh would love that.

Ds1 has always wanted one.. been a malteser for a while then past two years it's been a Star Wars Lego one.. I've brought a star wars Lego one already for this year to take with him for uni this year

Ds2 doesn't like chocolate (milk allergy) so I make him one, he unwraps a little something every day.. silly things from the poundshop though.. nothing extravagant!

Amazon definitely have the traditional picture only ones.
The kids get chocolate ones and I buy DH a traditional Christmas one.
It is a big deal every morning, we all have a guess to what will be behind the door:holly, a bell, wreath, angel, star, toy...
It is hilarious and addictive-and competitive! How will win the most guesses?!
