Clicking on letters

On the title screen, you can click on the letters and they will each do something different. This is what they do:
M - Makes Mario shrink or grow.
A - Makes the letter fall. Knocks Mario off if he's under it.
R - The letter opens an eye and starts walking around.
I - The color turns opposite and makes the music weird.
O - The letter blows up and changes the music.
P - Makes a field with things to click on and changes the music.
A - Yoshi runs by the screen.
I - Shakes the screen and makes the music weird.
N - Rolls the credits.
T - Allows you to color the screen.
