One day, an ox was passing by the pond. The proud frog looked at the ox and asked his friends, ‘Am I as big as the ox?” His friends, who were tired of hearing the proud frog boast about himself every day said that he wasn’t as big as the ox.

The proud frog was furious and wanted to prove his friends wrong. He puffed himself up to become bigger and bigger to show his friends that he could be as big as the ox. He huffed and he puffed and all of a sudden, he burst and that was the end of the vain frog!
