- Her favorite hobby is knitting and sewing, she even made Donnie's sock monkey

- Developed sentience after 73 years in the vault

- Her curiosity led her to being the primary nannybot who would accompany Donnie on his excursions and explorations

- Very charismatic, easily beguiles kids with her motherly charm. Kids try to stay in her good graces lest they earn her disappointment

- Is fairly permissible for a nannybot, she really only enforces the most serious of rules
