Who entered a scene once and died in that same scene in SHOLAY?

In Sholay, the ant that Jaya Bhaduri's character Radha crushes when she first arrives in Ramgarad technically enters and dies in the same scene. This is a clever, humorous interpretation of the question. Among human characters, Ahmed (the imitator) has minimal screen time, but the ant's appearance is literally just for that moment before being crushed, making it the most technically accurate answer to this playful question.
