The ghosts turn edible and invisible, like with the bonus items. The maze walls and all remaining dots turn invisible for the duration of the Pellet or item. The maze walls turn invisible for the duration of the Pellet or item. Only three ghosts will turn edible, with the fourth changing direction. All four ghosts turn edible, as in the original game. Eating a Power Pellet is unpredictable, causing one of the following events to occur:. Invisible ghosts are worth double the normal point values (starting at 400 and ending at 3,200) and their vulnerability time lasts longer than a Power Pellet. Eating a bonus item causes ghosts to turn both edible and invisible. Ghosts are faster and more aggressive, increasing the difficulty right off the bat. The point values of eating an edible ghost are yellow instead of blue, and a "3200" graphic was added (see above). The maze is teal green instead of blue. For example, the first bonus item resembles a Coca-Cola can. Most of the bonus items (barring the apple and Galaxian Boss) have been redrawn to resemble different foods. Pac-Man and Super Pac-Man's sprites are touched up, resulting in smoother and cleaner mouths. The sprites of the ghosts moving upwards also had their eyes moved down by 1 pixel. When moving horizontally, the Ghosts' eyes are one pixel closer together- a change also present in Pac & Pal. Vulnerable ghosts are now shorter and have a leaf sticking out of their heads(?). #Pac man ghost names plus
