Not sure why I haven't seen this come up before (or has it? search wasn't much help).

Anyway, the basic concept is replacing the normal bullets with a single slug projectile similar to Magnus line. The Slug deals normal damage (an oddity among gun puppies) with a chance to Stun. Its spawn rate places it somewhat uncommon, and is able to spawn in place of any other gun puppy with a few restrictions for scripted levels. Color scheme gives it a dull yellow tint (not gold), with the glowing ember on its nose typical of status puppies.

The desired coloring is mostly because I need to fill the Yellow slot for a Gun Puppy Voltron.
