Bug: If you try and offer Captain Dread something that he doesn't want, he turns around and faces Guybrush to decline the offer. If you then try and talk to him however, Dread's face appears on the back of his head, and he somehow then turns around again to face Guybrush.
Bug: If you stand in front of a bug or a fish and press start right after swinging a bottle at it, you can put another item in the bottle's place and turn it into another bottle. When this happens, the erased item cannot be recovered, and the new bottle will retain the limitations of the original item (for example, turning the Claim Check into a bottle will still be unable to be used by Young Link.).
Bug: Any time you pass through a portal keep holding the movement button in the same direction, sometimes when you are finished going through Spyro will move around but there will be no animation of him doing so. He just glides along on the ground.
Continuity mistake: At the end of this game, Trogdor announces that he's invincible, and demonstrates that he is at least immune to swords; but in the actual game "Trogdor" he is easily killed with a sword.
Other mistake: In the first case, when Phoenix is in the lobby, Maya hands him a document. The specifics say that it was received from "Maya Fay." However, at this point in the game, Phoenix doesn't recognize her (because he has amnesia), so there is no way he'd know it was from "Maya Fay."
Plot hole: When Umbride is about to use the Cruciatus curse to interrogate Harry towards the end of the story missions, Herminone says "Tell her. It's not worth another student dying." No students had died (not since Cedric Diggory anyway), were threatened with death or were in any kind of fatal situation yet. What is she on about?
Suggested correction: Exactly what she means. Cedric Diggory is dead so it's nothing worth Harry to die over.
Bug: There is a glitch where you can walk in the gray/green space that the place was created in any playground. You need a friend. You click on their name, then click "Whisper" and say "Can you teleport to me?" When you see the whisper that "(insert toon name here) is coming to visit you", wait a little, then go through the door. They will teleport near you, and outside of the door (and in the Grayspace). Then, if it worked, you can teleport to them and be in it too. This helps you get to the pillow glitch, which is accomplished by running around Donald's Dreamland in the Gray, and getting to the pillow. Then just jump.
Continuity mistake: When you use the Predator's vocal mimicry ability the Predator says lines from cutscenes you haven't seen yet as well as lines from scenes in which the Predator wasn't present to record them.
Plot hole: When Tails is flying towards Prison Island for the first time, he spots Amy on the island surrounded by enemies after mistaking Shadow for Sonic. There is no explanation given for how Amy arrives on such a guarded and fortified island. When Sonic asks her later, she says that she hitched a ride with Tails in his plane, but she couldn't have, as Tails spotted her on the island as he was flying in.
Suggested correction: Amy was talking about how she made it inside the prison, not how she made it to the island. There being no explanation of how she made it to the island isn't really a plot hole either way. It's just something that is never explained.
Other mistake: If you use an entrance that shows a wrestler's teeth on The Rock you will see that he has no teeth.
Continuity mistake: In the European version of the game, after beating the Normal Campaign, you can go to the Battle Maps shop and purchase Black Hole CO Zak, however when Hachi asks you to confirm the purchase, he is called Koal, not Zak. This is the US name, which they forgot to change.
Continuity mistake: In the scene where the Prince (wraith) jumps across the gap in the clock tower he gets knocked out by a Brute, but when the real Prince jumps the same gap, the Brute smashes through a wall even though he was already out of the wall when the wraith was knocked out.
Other mistake: At one point on talk radio show Chatterbox, Maria (Salvatore's girlfriend) calls up to ask Lazlow for romantic advice. In her call, she describes the events that occur in the game involving Salvatore betraying the game's protagonist and how Maria is falling for him. This conversation can be heard on the radio before the events have actually happened in the storyline.
Audio problem: In the last part of the game, if you play as Fong, Fong's voice will be the one guiding you, not Bruce's.
Other mistake: Inferi are known to be repelled by light and fire. Many times during gameplay, Inferi will appear outside during the day when they should only appear in very dark places. They even appear inside of caves with rooms that are brightly lit by torches.
Bug: In multiplayer Battle mode, you can keep shooting Green Shells over and over again which will forever bounce around the track if they don't hit a player, another shell or item, or environmental hazard. If you have enough Green Shells bouncing around, the game begins to not be able to handle all the activity and the smoke behind the shells will disappear.
Continuity mistake: Delfino Plaza: Most stages in this game are based off areas in other games but shrunk to a manageable scale. In Delfino Plaza, the buildings and everything are scale to Delfino Plaza in Mario Sunshine. But the tower with the large Shine Sprite has an error. In the Sunshine game, the big Shine Sprite is spherical like a ball with the extensions on it. But that same Shine Sprite in Brawl is more M&M shaped. A difference in shape not just size.
Other mistake: If you change your class of character after you die and go back to look at your body, it will have changed to the class you are now. For example if you are playing as a Spy and get killed, then change to a Pyro and go back to where you were killed, your previous body will still be there, it will now be a Pyro.
