In this Level, Players must fire birds, Pac-Man, And Miss Pac-Man at flashing dots in the first 15 levels while avoiding the ghosts, then shoot the ghosts in the next 30.

Miss Pac-Mans ability is the same, but when she runs into a structure it stops working.
In Pig Ninja, players must slice pigs. There are three sections: Classic, which includes birds which wen sliced end the game, and if three pigs are missed the game will also end; Zen, with only pigs, but each level is on a 1 and a half minute time limit; And arcade (On the same time limit), which has three power ups (Freeze, which stops the timer for 10 second; Frenzy, which adds a large succession of random pigs for bonus points; And double, which doubles all points within 10 seconds). Each level has a different score aim.
