Today’s City model is what appears to be a pair of (very small) soccer goals and a ball.
In Friends, we get a candle. (The hole near the top is so you can pass a string through to hang it on your tree, as all this year’s Friends models are ornaments.) There’s an extra 1×1 round trans red plate. Personally I’d rather see a flame element used here rather than just a transparent orange cone.
The Star Wars model is a minifig-scale (or droid-scale?) blaster cannon. Pew pew pew! Two of the extra 1×1 round trans red plates are spare ammo according to the instruction diagram, and the third one plus the trigger piece are just extra parts.
