Blipvent Calendar #10: It's All Kicking Off

Hmm, this is getting a bit weird. Do bear in mind though that I have to work with whatever is behind today's Lego advent calendar door. Anywaaay...

So the Skater Girl is a bit feisty and is evidently serious about stealing Our Hero from Tall Lady... she's built some kind of mad Snowball Catapult™ and is battering her love rival... this can't end well.
