Bricka, the building bricks cat she's been around a fair amount of time in TADS, and she seems alot more level headed and even helps people with sanity, altho she keeps breaking apart she always puts herself back together
She's also the main reason why Ice Pop haven't Abstracted yet
(BTW Abstraction in TADS is a bit different than in TADC, which instead of being glitchy monsters, they just become full on demon monsters that hurt other people)
