Spyro: Year of the Dragon has a completion percentage that can exceed 100%. By finding every egg, every gem, every skill point, and every secret, the total reaches 117%. Insomniac Games built a bonus reward for players who achieve this: a secret cinematic that extends the ending and features characters commenting specifically on the player’s completionism.
The 117% secret was not documented in any official guide published at launch. Insomniac included it knowing that the majority of players would never reach it — it exists purely for the subset of players who do not accept that the credits mean they are finished.
The Midnight Mountain homeworld contains the game’s most hidden skill points — combat challenges, time trials, and collection feats that have no in-game marker. Some require performing specific tricks in specific order. Several were not fully documented until community guides emerged years after launch.
The Sorceress, the game’s main antagonist, is also the only Spyro villain who survives the final boss fight. Her survival is part of a subplot that was never resolved because it was intended to lead into a fourth Spyro game from Insomniac — one that was never made after Universal acquired and then mismanaged the franchise. The Sorceress is the only loose end in the original trilogy, standing in as a structural marker of where the series was supposed to go.

Stumbled across this on a late-night session and couldn’t believe it. Your explanation finally made it click.
The attention to detail the developers put into this is insane. Most players will never see it but it makes the world feel so much richer.
