FYI this will take roughly 2 minutes (a little more) to to watch. Also, there are a couple sounds, so turn the sound on. Press the flag and watch what the pigs do. Also, put in the comments what school you think the smart pig / third pig / graduated from high school pig (though the school isn't necessarily real, and don't do that if I told you). If you click a certain place, and it is better to do it right after the opening, something special will happen. If you press certain keys on the keyboard, something special will happen (two of them are make it impossible, one of the two has a fix). Put in the comments which key you think it is. The reason for this is the talking pigs and wolf live in a magical fairy land. Figure out the "spells". Finally, there is a secret key that skips to the ending animation if you keep pressing it every time something shows up.
