Octopus and Rat
This tale belongs to the Oceanic Mythology.
One day, three terrestrial animals, the flying fish, the crab and the rat, joined a flock of birds to travel in a canoe. When a kingfisher drilled a hole in the bottom of the canoe, it was filled with water and sank. All the birds flew. The flying fish imitated them, but fell into the water and saw that he could swim. The crab fell on the reefs and saw that he could move smoothly.
The rat, however, was struggling to keep from drowning when an octopus passing responded to his cries of anguish and agreed to bring him to the coast. The rat refused to hang from the tentacles and so climbed to the head of the octopus, where he urinated and defecated on it. As it was so capricious, he would not jump the octopus and forced him to take her to the mainland to avoid wet feet. Then the rat, badly said the octopus that smacked his own head.
Upon discovering his droppings, the octopus was angry and that is why he has lumps on his head and always attacks fake rats used as bait by fishermen.
