Now ive seen alot of people asking about this morphID or the other heres a nguide to get what you want if you know creature name.
#NOTE: make sure you type .invincible to turn invincible on, port somehwere far from where you are.
1: get name of mob/npc
2: .lookupcreature <NPC name, do not include first letter
3: now use that Id to spawn the creature(.npc spawn <Number that appeared>)
4: target the NPC
5: use .npc info
6: Scroll up a little in your chat log, the "displayID" is the morph ID
7: .morph <ID YOU FOUND>
8: enjoy.
