The moods and movements of the snake changed in the changed circumstances. In the beginning he seems to be in a relaxed mood and his movements are also relaxed and leisurely. He sipped and ‘softly drank’ into his ‘slack long body silently’. But when the poet threw a log at him his moods and movements changed suddenly. He ‘convulsed in undignified haste’ and ‘writhed like lightning’. He disappeared all of a sudden into the horrid black hole.
