Press the up arrow for a surprise! Press the space bar just because it's fun to do so :)
How might the code be more difficult to read or maintain if the default names of Sprite1, Sprite2, etc. were used? Default names are hard to remember once you start using multiple of them because they are generic. It is hard to remember the specifics of each Sprite if there is only a number differentiating their names. It's like calling everyone with the last name Nguyen by their last name and then a number, like Nguyen1, Nguyen2, and Nguyen3.
