Pouch of Sounds

This magical pouch appears as a normal belt
pouch. As an action, a creature holding the pouch
can speak or make a sound into the pouch's
mouth, and then seal it. When the pouch is
unsealed, squeezed, sat on, or otherwise opened,
the sound that it was holding emerges at exactly
the volume that it was originally made. The sound
can be no longer than 6 seconds. Once the sound
escapes, it must be refilled.
Oh, god, it's so gross. Put that thing down.
