In some copies of games, often the game sometimes reads a part of an area wrong, or is confused while loading an area. You may have one of those copies. Like another, someone in the Stockyards always thought something is touching a mine, making it explode. Your game might think you were simply falling down through a ledge.

So I see I have to end this game without saving this Mudokon. Thanks for help to everyone, who tried to help me, but it was impossible ;)

i think there is a cheat that makes u become invincible? I dont know if it lets u survive big falls but you may as well use it to save just that mudokon
