See https://sourceforge.net/p/arianne/bugs/5767/ for why the current Elder Gargoyle sprite can't be used (it's a copyright image from Chrono Trigger, a SNES game by Square Enix). I have made a replacement Elder Gargoyle spritesheet that is a palette-swap from the gargoyle, venom gargoyle, and dark gargoyle spritesheets (which are all palette-swaps of each other). This eliminates any problem with copyright infringement... and I also think my version of an Elder Gargoyle looks pretty nice, too. I tried to find free images for use in games that looked like a gargoyle online but none of the ones I found quite fit, and this one is better than anything I could find online. Plus this doesn't require adding any license text to the game or anything. So I am submitting this as a patch, to use this spritesheet in replacement of the current one for Elder Gargoyles.
