Simile is a figure of speech which is used for comparison of 2 unlike things using like or as for example : white as snow , red as an apple. Similes are like metaphors. But metaphors are not the same as similes. Authors use simile to present their writings as exciting as a spontaneous show of fireworks. Here in the statement "They leaped like deer on the moon" which is an exaggeration but the use of direct comparison showing excitement.
