Continuity mistake: In the scene early on in the movie, where Lord Beckett and Elizabeth are talking, behind Lord Beckett you can see a man sitting on a seat suspended in the air by two ropes, apparently working on a ship or something of that nature.

Continuity mistake: On the island, when Jack says, "Yes, it does. You're sitting on it," the compass lid faces away from Elizabeth, but in the next shot as Jack shoos her away, the compass faces her; and the rope changes position too.
Continuity mistake: When Elizabeth walks over to the deck rail and notices Jack sneaking away in the long boat, her leather strap hangs from her left shoulder to her right hip, whereas in all other shots she wears it the opposite way. This is not a flipped shot - note Cotton's shirt tear. (02:06:25)
Continuity mistake: When the monkey steals the cloth with the key drawing, Jack shoots him and the monkey drops it on deck. Before Marty picks up the cloth, its position on deck differs.
Continuity mistake: When everyone is fighting on Isle Cruses, Jack is standing behind Will and he hits Will in the head with an oar. In the shot right after that, Jack is no longer standing behind Will. Will is reacting to getting hit so you know it was right after, and Jack wouldn't have time to move. (01:58:15)
Continuity mistake: After Beckett tells Will to get the compass, in the next shot of Jack aboard the Pearl, as he plots the map, things on the table - such as the compass, change position between shots.

Continuity mistake: When Norrington, Jack and Will bang away at each other on the beach, in the shot facing Elizabeth as she puts her hat back on, behind her Ragetti runs ahead of Pintel (3-4 ft) as they steal the chest. Next shot, it is Pintel in the lead as they run off. (01:49:00)
Continuity mistake: After Will slides down the sail, just as he grabs hold of the mast line, the cut sail is only tied down at its corners. After he puts the knife in his mouth, the sail is also tied down directly under the cut. (01:36:10)
Revealing mistake: When Will, Gibbs, and the other pirates climb up the cliff's 90º rockface, their hair, jewelry, etc do not reflect the gravity which would naturally affect them, despite any wind.
Continuity mistake: When the cannibal walks across the bridge and sees some prisoners fall to their death and the others escaping, there is a long stick, which has a black design on it, threaded through his lip. When he arrives back at Jack's roasting, the stick's design is very different. (00:36:10)
Continuity mistake: When Will hangs with his hands bound, the ruffle on his shirt cuff goes up and down and up again.
Continuity mistake: When Will, Gibbs and the rest are in the ball cage and escaping the cannibals, they roll down a hill and hit a tree, which they then roll up. This would be impossible unless the weight is evenly balanced throughout the ball completely. (00:37:50)

Continuity mistake: During the scene in which the Black Pearl endures a strong storm and heavy rainfall, Captain Jack Sparrow's bandanna is soaking wet. In subsequent scenes, only moments from the storm, his bandanna is completely dry.

Answer: There is a scene after the credits of "The Curse of the Black Pearl": the monkey got back to the cave and took a coin. That way he turned undead again.
