To grab any of the sounds, click "See inside", select the pink and yellow present, view the Sounds tab, and drag the sound icon into your Backpack. In your other project, drag it out of your Backpack into the Sounds tab of a sprite or background. To grab the present itself, drag it to your Backpack, and then in your other project, drag it from your Backpack into the Sprites list.
