If Turducken doesn't appetise, how about Whole Stuffed Camel:

And the ULTIMATE Turducken:
In his 1807 Almanach des Gourmands, gastronomist Grimod de La Reynière presents his rôti sans pareil ("roast without equal")—a bustard stuffed with a turkey, a goose, a pheasant, a chicken, a duck, a guinea fowl, a teal, a woodcock, a partridge, a plover, a lapwing, a quail, a thrush, a lark, an ortolan bunting and a garden warbler—although he states that, since similar roasts were produced by ancient Romans, the rôti sans pareil was not entirely novel. The final bird is very small but large enough to hold just an olive; it also suggests that, unlike modern multi-bird roasts, there was no stuffing or other packing placed in between the birds. Some of the birds used are today endangered.
