This copy of World.sfc has had the Grendel Mother removed and has been
altered to allow the breeding of grendels.  If you want to alter a copy
of you own custom world, use a hex editor and do a search and replace
as follows.

Search for: doif gnus eq 2
Replace with: doif gnus eq 9

This will allow the grendel behave just like a norn.  You will still
need grendels with reproductive organs if you want to breed them.
