Roysten

"Please help me! Because if I die, your garden will smell of dead fish"

- Roysten

Roysten is Banjo's pet goldfish. He appears in all of the games in the Banjo-Kazooie series but is usually a background character (except in Banjo-Tooie), serving little purpose aside from showing up in humorous/dangerous situations.

Banjo-Kazooie
He appears on a shelf in Banjo's House swimming around unhappily then tapping the glass of his bowl. Near the end of the game Mumbo Jumbo is seen grilling Roysten on a barbecue.

Banjo-Tooie
In Banjo-Tooie, he is knocked off the barbecue (although you can see him in banjo's house in the intro) when Gruntilda blows up Banjo's House and becomes trapped under a boulder that must be smashed using the Bill Drill ability. Once Roysten has been rescued and released into the moat around Spiral Mountain, he teaches Banjo and Kazooie how to swim faster and increases their air capacity from 6 to 10 bubbles. When Mrs. Bottles makes Bottles eat her burnt dinner, Roysten can be seen on the plate blinking and is all burnt.

Banjo-Kazooie: Grunty's Revenge
Roysten makes a cameo appearance in Banjo-Kazooie: Grunty's Revenge, still stuck on the barbecue from Banjo-Kazooie (as this game takes place between Banjo-Kazooie and Banjo-Tooie).

Banjo-Pilot
Roysten appears in the background of the trophy room inside his fishbowl.

Banjo-Kazooie: Nuts & Bolts
Roysten appears in his fishbowl as a part in Banjo-Kazooie: Nuts & Bolts. He appears on the main menu and is also a Stop 'n' Swop part. This is used only for decoration purposes and has no conventional use. (NOTE: Banjo-Kazooie for the Xbox Live Arcade is required to collect the Stop 'n' Swop items). The part is required to fully make the L.O.G. Banjo vehicle and one of two vehicles (Humba Boat 2) to have a Stop N' Swop part.
