block (xmod) (ymod) (zmod)
go to: X:((X+xmod)/(Z+zmod)) Y:((Y+ymod)/(Z+zmod))
.
make sure to turn on run without screen refresh on the block and have variables X, Y, and Z.

judging from the placement it should be the intestinal tract plus a bit of liver showing at the top, the intestines are mostly just a long thick line with weird creasing and the liver is mostly just a weird doorstop shaped thing
