The term 'pink shot' may refer to any one of three enemy hazards found in Keen.
In Keen 1 these are the shots produced by Tank Robots; patches relating to these are on the second section of the page.
In Keen Galaxy they may refer to either of two nearly identical 'raygun' hazards. These two hazards are Patch:Enemy shooter (Keen 5) and Patch:Enemy shooter (Keen 6).
The most closely related enemy is Patch:Enemy shooter (Keen 3) which uses orange shots, as well as the dart gun in Keen 4 and the watermelons in Keen Dreams.
