Mrs. Bottles

Mrs. Bottles, also nicknamed Mrs. B, is the wife of Bottles, the mother of Goggles and Speccy, and the sister-in-law of Jamjars. Her first and only role is in Banjo-Tooie, where she lives with Bottles and their kids in an underground tunnel. Mrs. Bottles has several curlers in her hair, and is always seen holding a mug which reads "B-T", an acronym for Banjo-Tooie.

Banjo-Tooie
In Banjo-Tooie, when Banjo and Kazooie first meet Mrs. Bottles, she wonders why Bottles is late for dinner, unaware that he was killed by Gruntilda's spell. Banjo does not want to tell Mrs. Bottles about what happened to Bottles, and although Kazooie is fine with relaying this message, both of them decide to not tell her. Unaware of Bottles' death, Mrs. Bottles gets irritated and deliberately leaves his dinner overcoocked.

Near the end of the game, when Klungo and King Jingaling show up to Bottles' house for a party, Mrs. Bottles scolds Bottles for being so late and forces him to eat his burnt dinner. Bottles tries to explain that he had been killed and later revived, but Mrs. Bottles does not believe him. When Mrs. Bottles sees Klungo and King Jingaling, she asks who they are. The two explain that they came to celebrate Banjo and Kazooie's victory over Gruntilda. Mrs. Bottles decides to make scones for the occasion.

If Banjo and Kazooie return to Bottles' House before their final battle with Grunty, the door is locked. From inside the house, Mrs. Bottles tells the duo to first deal with Gruntilda, and then Klungo asks her for another scone.

One of the Tower of Tragedy questions asks what Mrs. Bottles' first name is. "Milky" and "Betty" are the two incorrect answers, and the correct answer is "It was never mentioned."

When Banjo and Kazooie complete their adventure and visit King Jingaling, he tells them that Mrs. Bottles, whom he calls "Mrs. B", is a wizard cook", and that she makes delicious scones.

Banjo-Kazooie: Nuts & Bolts
In Banjo-Kazooie: Nuts & Bolts, it is mentioned that she and the children left Bottles due to the trauma of his death, despite that they did not acknowledge his death in Banjo-Tooie. When Banjo and Kazooie ask Bottles in Showdown Town, he tells two conflicting stories of Mrs. Bottles being run over and killed by one of Gruntilda's vehicles, and that she is still living happyly in Jinjo Village. Although Bottles acknowledges the conflicting information, he does not bother telling the real story to Banjo.
