A scribble-alphabet version of the 死んだ. A sort of C. Since the 死んだ are often forgetting important things (basic things, like how to talk to think to tell time), the basic machinery of this place makes great efforts to surround them with reminders, and organize them into didactic activities. Here, they 踊り gaily, repeating a localized version of the Alphabet Song... not as sung by children however, so maybe it would be better to call this tune the Alpha-zed Turn.
