I loved the idea of playing a fat frog in D&D and overlayed that onto Grung. I was having trouble getting character portraits to come out consistently, so I made a LORA to attempt that. The key token is "Grung" and "X skinned" (green skinned, etc.). For an example prompt, try "Grung, green skinned, squat and wide, standing in front of a corkboard with red string, candlelight illumination, wearing chainmail, a swampy detective office with old tomes, maps and scrolls"
