 * Fire Crab: There are only two Fire Crabs in the whole game, in the fire seed level. It can shoot fire out of its backside. Cast Flipendo on it twice to knock it over.

Trivia

 * Peeves does not appear in the film, but is battled on a regular basis in this game.
 * The Forbidden Forest part is not included in this version.
 * In the film and book, Harry's broomstick is jinxed in the first Quidditch match. In this version, both Quidditch matches have no Jinxed brooms or accidents.
 * In the book, Quirrell summons ropes to tie Harry by snapping his fingers. In the film, Quirrell snaps his fingers to make fire surround the area. In this game version, Quirrell moves his hands to conjure fire around the area.
 * Norbert seems to appear early in the game, unlike in the book and movie where he appears nearly at the end of the story.
 * Originally Reparo, Verdimillious and an unnamed spell were to appear in this version of the game. Also Incendio and Wingardium Leviosa were to have more uses.
 * The Dursleys were to appear in this version of the game because they have their model files still in the game.
 * Harry constantly fights Draco on a daily basis. Though, in the book and movie, Harry doesn't fight Draco at all until Year 2.
 * Harry gets trapped in the dungeons during Potions class.
 * Dumbledore, when greeting Harry Potter in the beginning of the game, tells him about a story about finding a room with a lot of toilet pots, and the next time he found lots of fire tortoises. This was actually taken from a brief conversation Dumbledore had with one of the ministry officials during the Yule Ball in Harry Potter and the Goblet of Fire.
