this is TAB-i, aka just tabi. they're izzy and fletch's robotics class final project that at first just didn't turn on because they did such a shitty job, so in an act of desperation fletch used magic to give it a conscience so ava (their teacher) wouldn't fail them. and since fletch is shit at magic instead of giving it a normal squirebot-like conscience he gave it a cat conscience by accident! initially, they were given a good grade for giving their squirebot such a responsive and lovable personality, once they were done being graded they found that they just. couldn't turn them off. ava quickly found out that they cheated with magic and gave them a D-. she was very impressed with how they combined tech and magic, but unfortunately it still counts as. Cheating. anyways! since they couldn't just turn off tabi they kept them around the academy (originally to hunt mice but they quickly found out they only hunt computer mice) as like a class pet. they don't speak, but they do meow and purr like an overheating ps4!
