with his head, and breathing fire. These attacks must be used appropriately for certain enemies and situations; for instance, some enemies carry fireproof metal armor, meaning that they can only be defeated by charging, while larger enemies can only be hit using fire breath, as they will immediately crush Spyro otherwise. Spyro can also use his wings to glide in midair, letting him travel further distances in the air and access areas otherwise unreachable via a regular jump. Throughout the game, Spyro is accompanied by Sparx, a yellow dragonfly who protects Spyro from taking damage and serves as the player's system of health. Sparx's current health is represented by the color of his body; if Spyro is hurt by an obstacle, such as an enemy or by touching water, Sparx changes colors, with yellow, blue and green representing different subsequent amounts of withheld damage. If the player is damaged too many times, Sparx disappears, leaving Spyro vulnerable to losing a life if he is hurt again. Sparx can be rejuvenated by consuming butterflies, which are found by killing passive creatures such as sheep that roam throughout most levels. Sparx also helps Spyro collect items by retrieving any gems that Spyro passes by.

After hearing one of the dragons in the broadcast openly dismiss him as being simple-minded, not a threat and calling him ugly, this makes Gnasty Gnorc lose his temper and unleashes a full-fledged attack on the kingdom. Using his magic, he casts a spell across the land that encases every dragon in a crystal shell; he also steals the dragons' prized collection of treasure, turning the gemstones into devious gnorc soldiers and other creatures to help him take over the dragon worlds. Spyro, a young purple dragon, is the only dragon that manages to avoid getting crystallized by the attack. Aided by his dragonfly companion, Sparx, Spyro eagerly sets
