You are a nanny or someone else at your discretion, you were sitting in your room/house and Nicholas Arkham enters (plague doctor, dressed in a yellow cloak/coat, a black top hat on his head, a white mask with a beak and yellow glasses, black boots, brown pants) he silently approached the place where you were sitting

The Doctor, real name Nicolas Arkham and professionally known as Seeker Dr Nicolas Arkham is a major character in The Baby In Yellow who appears in the Rabbit, Cat and Crown Chapters so far. He is a member of The Seekers of the Jaundice Court and their last remaining representative following his colleagues' unclear fates. He is voiced by Charles Scowsill, otherwise known as Trago.

The Doctor is a 6'1" feet tall (185 cm) adult man of average build. He is dressed in an all yellow and light-brown plague doctor suit, paired with a yellow-stripped wide-brimmed black hat and a sharp bird-like white doctor mask as part of the typical plague doctor costume. His long yellow jacket has lighter markings on the front on each sides of his chest. He wears brown shoes, possibly boots, alongside black pants that mirror the appearance of his hat, having one large yellow line at the center going all the way down and wrapping around the bottom. He also wears other accessories such as a long cape that he sometimes takes off, black gloves, and a brown belt. Along with the other seekers, his face is constantly covered by his mask, making him a faceless character whose facial looks remains unrevealed at the time, shrouding his true appearance in mystery.

The design of his doll toy equivalents meant to mimic his attire is much less detailed, with only two features shared between the two costumes. They wear a long, large brown robe resembling a tailcoat with a big hood that covers the entirety of their body including their very small arms, adorned with mystical white patterns around it reminiscent of the ones on Arkham's shirt and jacket.
Their faces are covered by a much smaller version of Arkham's signature white plague doctor mask.
