One of the most mysterious robots, excluding Eerie, that the Professor owns. Syliavavé was not made by him, but was rather given to him as a gift. He found her as a box of parts, at his doorstep. Said box contained extremely detailed instructions that clearly stated that if one thing was out of place she wouldn’t function properly. Once she was properly built, the Professor gained new instructions, to find a room matching precise measurements, and set Sylviavavé up in it.
