The first AoK modpack ever placed in the Blacksmith changes one of the two marlin fish in the AoK .drs to that good-ole dolphin from the beta version of AoK! The frames came from a gif animation of the same dolphin. (NOTE:YOU STILL WILL BE ABLE TO USE THE OTHER MARLIN IN YOUR GAMES OR SCENARIOS)
The dolphin's .slp file is safely openable with no known errors.
