Behaviour: Follows the player under ground yet does not attack.
Name: SAND_CREATURE Health: 500
Name: SAND_CREATURE_FAST Health: 500
BUG: Does not use walking (here: crawling) animation while moving.
NOTICE: The second variant is slightly faster than the first one.
TIP: If you kill it by an admin command (for example /npc kill all) it will die with frightening scream crawling up on the surface. Good to scare someone...
