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.).
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.
Continuity mistake: At the end of episode five, Luke has had his hand cut off by Darth Vader. When he falls into the Millennium Falcon, if you look very closely, he still has both of his hands. In the next scene, his hand is gone again.
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.
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.
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.
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.
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.
Character mistake: In the opening cinematic (before you press start), the group hears a witch crying, and Bill and Zoey go to investigate. Louis and Francis stay outside to keep watch. When, in the dark, Bill and Zoey approach the witch, Zoey puts her flashlight on the witch and Bill immediately says, "lights off!" Now here is the confusion - Bill knows it's a witch, so shouldn't he know what they sound like and not enter the room in the first place?
Continuity mistake: Mob Rules: When Martin runs into the road and tells Ned to stop his car, there are two white lines across the road in front of the car. After Martin drives off, the two white lines across the road have suddenly vanished.
Continuity mistake: In the game's opening scene, MegaMan has blue hair. In the end scene, his hair is shown as black.
Revealing mistake: When fighting Gohma on Dragon Roost Island, when Link uses the grappling hook to grapple Valoo's tail, some of the rope goes through the tail as it wraps around.
Bug: If your computer or connection lags too much on co-op mode, sometimes you will lose connection and be removed from the game back to the menu. Sometimes though, when the connection is lost, the screen just turns black with the spinning Pentagram at the bottom as a loading screen, but it just stays there. You are stuck. You have to close the game down and restart it.
Bug: Use Kirby and eat Yoshi so you copy his eating ability. Then eat Yoshi to turn him into an egg. The person playing as Yoshi must quickly mash buttons and the control stick to break out. When Yoshi is free, he will be smaller. This can be done over and over again, making Yoshi smaller and smaller. He can even get as small as a single pixel.
