Walking through the forest, you heard a plaintive bleating and went to the sound in Lamb Escape. Very soon you went out into the clearing and saw the one who made this sound. A little lamb sat and cried in a cage, and a goat stood on top of it and could not help the poor fellow in any way. Unlike an animal, you may well contribute to the rescue of a captive and this does not require brute physical strength. If you have ever solved jigsaw puzzles, sokoban and others, it will not be difficult for you to open all the locks and find the key that will open the lock on the cage in Lamb Escape.
