im looking into certain stuff because I have a certain idea about something but I usually see 2-3 certain animals connected
in the picture. its usually a Crane and a Minogame (old ass turtle with moss that looks like hair on its shell) and occasionally a dragon. I know these 3 are related somehow but im not sure exactly. can someone please explain?
