How do we know which snowballs we can actually use to throw at other users?

((I know it isn't time yet but I'm sorting though my vault))

I believe Subetalodge has the most complete list (click! I did a notes sorting for "throw this" since the throwables all have that), but the ones that can't be thrown are apparently only the Snowball, Radioactive Snowball, Incoming Snowball, Snowball Bomb and I believe one or two snowball items that are actually wearables c: These come from battle / random / etc. Basically you can only throw what restocks in Avalanche Emporium, I think.

Oh very cool. Thank you much!
