Cinner prepares to fire the drugged dart.
Sleep-inducing projectile fired from a handheld gunlike device.
The dart is fired by an unnamed C.I.N. agent on the orders of his boss with the intention of drugging and kidnapping inventor Doctor Egghead.
However, it hits Maxwell Smart, who with Agent 99 is guarding the doctor. Nevertheless, the kidnapping still succeeds while Smart and 99 are distracted.
[Comic Strip Story #7 (Unofficial title: "Doctor Egghead")].
This drug is likely the same as the arrow-delivered "sleeping drug" previously used by C.I.N.
