Fodder is the collective name for small creatures that Spyro can kill to regain health. If a fodder is killed, its body will disappear, releasing a butterfly for Sparx to eat. Starting with Ripto's Rage, every tenth butterfly released is a special extra life butterfly.
The Sheep fodder creature has appeared in every game of the first Spyro the Dragon series
The Bat fodder in Spyro the Dragon appear to be the only hostile fodder in the series, they will not hurt Spyro, but they will fly and circle around him instead of fleeing like most other types of fodder.
