Golden Feathers are used to perform the Wonderwing ability. Each Golden Feather allows Banjo and Kazooie two seconds of almost-complete invulnerability. Golden Feathers are quite rare, usually being found in no more than pairs. Kazooie can only carry 10 of them (or 20 when Banjo finds Cheato and types in GOLDFEATHERS on the Treasure Trove Cove) equating to 20 seconds of Wonderwing time (or 40). The initial amount is 25 in Banjo-Kazooie: Grunty's Revenge.
