References in the Banjo-Kazooie series

Many games made by Rare have references to other games hidden within them, and the Banjo-Kazooie series is no exception. From names of characters to pieces of music, there's another cameo around every corner if you know what to look for.

Banjo-Kazooie
In the Grunty's Furnace Fun game, among the wrong answers for a question regarding Nabnut's name is "Conker the Squirrel," a reference to the main character from Conker's Pocket Tales for the Gameboy Advance and its M-rated sequel Conker's Bad Fur Day for the Nintendo 64.

Banjo-Tooie
Speccy, Bottles' son, wears a hat which bares a resemblance to the one worn by Ash Ketchum from the Pokémon franchise.

Other games
In the file selection area of Conker's Bad Fur Day, Banjo's head can be seen as a trophy mounted over the fireplace. There's also an umbrella handle which looks like Kazooie's head.

Both Banjo and Tiptup appeared as selectable characters in the Donkey Kong spin-off Diddy Kong Racing for the N64. The game was actually released several months before Banjo-Kazooie, and as such Tiptup is usually considered to be originally from Diddy Kong Racing, although the two games were in production at the same time, and the release of Banjo-Kazooie was also delayed.
