I remember ‘Kreegah’ as a sound effect from an old Tarzan comic.  Probably a Weird Worlds, possibly Tarzan Family, not sure, my memory isn’t the best.

An onomatopoeia is one of the hardest things to write.  Some of the sounds you can make, and do make to yourself in the quiet of your own home where no one can hear you being an idiot, are hard to wrestle down and pin consonants too.  And there’s always the risk of overdoing it, cluttering things up with a bunch of random letters that are impossible to make sense of.  If that ever starts to happen, be sure to let me know.  The fix will be a week of completely silent strips, because we all know the fix to any problem is a pendulum swing in the opposite direction.
