Trumpet

Trumpet is one of Xigbar's weapons in Kingdom Hearts 358/2 Days.

Design
As the name suggests, it is a pair of trumpets. They shoot projectile sound waves from the trumpets' bells, and make the sound of a trumpet as Xigbar shoots and reloads. They only carry twelve bullets at a time.

It is also notable that since the description for Mystery Gear states that it brings out the user's personality, this may be a reference to the fact Xigbar likes to "toot his own horn".
