Aqari

they're a rat robot. lemme copy paste what i wrote earlier. essentially, the idea is that they're a rat, but they're a robot, but like, they act as a living aquarium. they probably work at a zoo or something and house a rare species of fish. with their robotic and tech features, they can always keep things at a good temperature. the zoo/aquarium/wherever they work has them going out into the zoo/aquarium place and telling people about rare and endangered sealife
