The homograph of "I couldn't stop watching the stop cub search for its mother" would involve changing the meaning of the word "stop." In this context, it could be interpreted as "I couldn't stop" (to cease) and "the stop" (a designated place) for the cub's search. Thus, the sentence might imply that while observing a location, the cub was seeking its mother, blending different meanings of "stop."
