Ive got both these, I thought they were for use in the snowtapult, maybe open that box to get some snowballs, It seems odd that neither of them are usable in the way I thought. They are both items that go in your armory, the box doesnt even say what it does, Im really just commenting on them so maybe this is the wrong thread?
here they are:

I don't know if those used to be able to be used in the way you're describing, but I'm pretty sure that for a while now the Snowtapult has only accepted snowballs that can be bought at the Avalanche Emporium.

you can start a thread in Feedback. Staff do pay attention.

Both of these items are very old, and neither ever worked in the Snowtapult. If you want to know about an item without buying it, you can look in the Item Directory Building in Centropolis or the fansite Subetalodge.
