For an even weirder reason, you can find another snowball inside a snowball .__.;
Wow, I haven't seen that yet.
I found 2 snowballs inside 1 I picked up and eventually after throwing them all nothing was inside the last one!
That really made me laugh. It's almost like a matryoska (I have no idea if I spelled it right) snowball, too bad the last one had nothing.
