Making his debut in Banjo-Kazooie
, Roysten would swim around repeatedly in his fishbowl and tap the side of the glass every so often. It isn't until the end of the game that Roysten's life becomes more eventful, where Mumbo Jumbo
tosses him on the barbecue grill to celebrate the defeat of Gruntilda
In Banjo-Kazooie: Grunty's Revenge
(the next chronological game in the series), Roysten is making a home out of the pool of grease in the bottom of the grill.
When Gruntilda fires a destructive spell at the Banjo home in the beginning of Banjo-Tooie
, Bottles isn't the only character to feel it. The barbecue grill is destroyed and Roysten is trapped under a big rock. Begging to be freed, Banjo
break the rock with their newly-learned bill drill move, transport Roysten to the nearby river, and in return are taught how to increase their swimming speed. By the end of Banjo-Tooie, the crew show themselves to be as thoughtless as ever when Roysten is blackened to a crisp, about to be eaten by Bottles
Somehow surviving his closest ordeal yet, Roysten is later seen in the classroom of Grabbed by the Ghoulies
' Ghoulhaven Hall
. He is once again in a fishbowl, tapping the glass three times at set intervals just like in Banjo-Kazooie. It is unknown how he got here.
A year later, Roysten makes a cameo in the Trophy Room of Banjo-Pilot
In Viva Pinata
and its sequel, Roysten is seen in the Paper Pets shop. The local furry Miss Petula is balancing the fishbowl on her head, with Roysten leaping out every so often. Roysten is the only non-Pinata animal in the game.
Back in the Banjo home for the third time, Roysten in Banjo-Kazooie: Nuts & Bolts
looks considerably more disgruntled than normal, likely due to his redesign. Roysten is also a vehicle accessory in the game, where he actually swims around in his bowl as you drive around.
