These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Breather Boss: Scorch. While the developers were smart enough to make him fairly challenging because he's intended to be a Climax Boss, he comes after Spike and the Twin Dragons. The next Sparx boss you can fight, the Giant Stingray, is That One Boss for Sparx, and after THAT is the Final Boss... out of all of them, once you get all of these bosses' patterns down, Scorch is the easiest.
Catharsis Factor: One of the first things you can do post-game is chase down Moneybags and kick the ever loving crap out of him in order to get back the gems you've spent over the course of the game.
Complete Monster: The Sorceress's first act has her stealing every unborn dragon so that she can restore magic to her home world. While her Dragon Bianca claims she is a Well-Intentioned Extremist, the Sorceress chastises her for thinking this. She states that she wants to kill three hundred infant dragons for their wings, which she will use for a spell to make her live forever. When the horrified Bianca asks why she has to kill them, she replies that she doesn't; she just doesn't want them squirming around when she cuts off their wings. This persuades Bianca to pull an immediate Heel-Face Turn.
Contested Sequel: Some feel like it's the best of the original trilogy, managing to build on the set formula from the first two games. Others feel it's the weakest of the trilogy, for the above reasons stated in Broken Base.
Game-Breaking Bug: Flaming Fluffy, the cat-shaped fairy that gives the egg to Spyro upon completing Cloud Spires, at the same time he (or she) speaks with you will not trigger the cutscene. Speak with Fluffy again, and he'll act like the cutscene has played, but will not give out the egg and just disappear into an invisible portal. This will trick the game into thinking that the realm has not been completed. Entering and exiting the sub-level with the sun seeds will bring Fluffy back, but he cannot be spoken to. The only way to complete the realm is to exit and reenter Cloud Spires.
Narm: The Sorceress boss battle on the original NTSC version. Due to a glitch, your final battle is being conducted to the tune of Sunrise Spring. The battle was SUPPOSED to have it's own theme as it is present in the disc, though this was fixed in the Greatest Hits version.
That One Boss: Spike. He's similar to Ripto, attacking with energy balls that are ridiculously hard to dodge consistently and, in the second and third phases, can take the powerups for himself. In addition, the first phase requires incredible precision and speed to the point where you will likely get hit, and the latter two phases, while easier, are still a challenge.
What Do You Mean, It's Not Symbolic?: In Evening Lake, there is a whale swimming in the deeper regions of the lake. If you swim up to its mouth, the whale will eat you, revealing a dragon egg inside its stomach. The dragon inside the egg is called "Jonah." On the other hand, a lot of these dragons have jokenames.
