#
# This script will teleport the player to a food-filled map. It only works
# once a (ingame) day.
# Applying the tome while in the map will teleport the player back to his starting place.
# Book can only be applied when in player's inventory, so player can get back to the world.
#
# Map is generated by the script itself, and given a unique name to avoid collision.
#
# Player is replaced with a statue so the spot stays free during his trip.
# To avoid colliding with an existing map, created map will have a unique map.
# Everything in the map is randomly chosen.
