meaning of finery

However the humans living for the spaceship were different to the humans who're living on the planet now. They were so fat that they are struggling to walk. they travelled around in motorised chairs with a monitor and cup & straw attached, chatting on phones and when they happened to fall out they just laid there until a robot came along and picked them up. The adults were fat, the children were fat! They just laid around all day consuming doing no exercise what so ever and to quote the captain, "Computer, define dancing". This is just an account but good stories, especially children's stories needs to have a morale towards the tale and Wall-e just isn't exception. The story is approximately how a humans had treated planet earth so while living there that they just exhaust space to dispose of all of the rubbish that they created. All the humans had left earth to travel continue to exist a spaceship for 5 years as the mess was settled by robots but the earth became toxic and killed everything that was living except a strange bug or two. 700 years later the humans remained living aboard the spaceship waiting for indications of life in order to return.
