According to the Bible, Noah built an ark and brought a pair of each animals on board to survive a flood. When the ark ran aground Noah told the animals to go forth and multiply.

Noah gathered some driftwood tree trunks and built a platform for the snakes. Even adders can multiply when given a log table.
