It is HAM CATCH weekend someplace in Japan. Every ninja in that place has to catch five HAM throughout the day. Normally, this is an easy task, but OH NO!!! YOU SLEPT THROUGH THE ENTIRE DAY!!!! Catch five HAM before midnight (which is fairly soon). IT IS OF THE STRESSFUL FUN!
The game is particularly slow on most of the personal computers it is played on. Medium and low qualities are of the recommended.
