Shitai-san (死体さん, 'Mr. Corpse', pronounced more like "shee-tai" in regular speech) is a character found in Madotsuki's dreams.
He is a zombie that is found on The Road section of Dense Woods B surrounded by traffic cones. Interacting with him gives you the Stoplight effect, it is an obvious reference to traffic accident deaths.
Using the Cat effect near him causes him to twitch unnervingly.
Shitai-san is one of the more popular NPCs in Yume Nikki. Some fans cosplay as him and there is even a 'Shimeji' of him.
Trivia
