Al Dente Minnow.  Treated synthetic suede, jerk style fly/flure designed to have a slow sink (almost suspending) rate once the air is worked free and the material is fully saturated with water.  SF blend material tail.
Hollow body that can accept a 3mm to 4mm rattle (not included) if needed.  Rattle can be inserted into the tail and worked forward into the main body cavity.
2/0 @ 3”
Recommend:  8 - 9 weight line.  Sinking or floating
Tip:
For faster fly saturation and air removal, submerge fly and squeeze 6 times minimum.
