Betette

"Thank you! Earthlings not all brain dead!"

- Betette, Banjo-Tooie

Betette is a member of the alien family that is encountered in Banjo-Tooie and Banjo-Kazooie: Nuts & Bolts. Betette has blue eyes, wears a pink alien jumpsuit, and holds a blue rattle. Due to this alien wearing pink, it is proven to be a girl.

Betette, along with the rest of the alien children, is first encountered after their spacecraft crash lands in Hailfire Peaks, and helping them can earn the duo a Jiggy. Later on the series, it is revealed that the alien family has returned to their home in the Terrarium of Terror.

Banjo-Tooie
In order to get a second Jiggy from the alien family, Banjo and Kazooie must rescue the three alien offspring after Mumbo Jumbo uses his Life Force spell to revive Alph after their ship crash-lands on the Icy Side of Hailfire Peaks. Each of the alien children, including Betette, remain hidden until they sense Alph's presence, after which they appear and can be rescued.

Betette is found under a sheet of ice located just in front of Wumba's Wigwam and by the ice platform. Kazooie must Bill Drill the ice sheet to free Betette. After removing the obstacle, Banjo and Kazooie find Betette dead. Banjo humorously comments that she needs "beak-to-mouth resuscitation". But Kazooie, who is too cowardly to do so, quickly refuses. Banjo then says that this is a job for a professionally qualified doctor, referring to Mumbo, who's abilities must be called upon once again to in order to revive Betette. After this, she gets out of the hole and runs to her family.

Banjo-Kazooie: Nuts & Bolts
The alien family appears in Banjo-Kazooie: Nuts & Bolts in cryogenic capsules in the Terrarium of Terror. The aliens live in an underwater dome in the Terrarium, however one them is separated from the rest of the family, and is found at the very top of the level. The capsules that the aliens sleep in can be smashed open, although they remain unresponsive even once they're freed. Strangely, only five of the aliens appear in this game, and the sixth one is never mentioned.

The mission "Family Misfortunes" involves bringing the solitary alien at the top of the Terrarium down to be with the rest of the family. This mission is hosted by "B-066Y", who believes himself to be the family's long lost cousin.
