His sons, Ham, Shem and Japheth "build the ark from dawn to dark and make a lot of noise" with some help from the animals, while their wives load up food supplies to see them through the flood and Noah's wife is washing clothes.
40 days later, the storm recedes and a dove, carrying an olive branch, flies back to Noah and his family to signify that land has been found.
They lower the gangway and the animals and their offspring all come back out onto dry land (the ark, in this case, resting atop a tree).
The Pomp and Circumstance segment of Fantasia 2000, also based on Noah's Ark, makes minor references to this short.
The short was released on December 4, 2001, on Walt Disney Treasures: Silly Symphonies - The Historic Musical Animated Classics[3][1] and on the UK VHS of Dumbo as a bonus feature.
