Hm, you can enter this graveyard earlier, but in order to let Shrimpo appear, you need Apollo to come first! Otherwise the tombstones in the NE corner will have no effect. Hitting them in the correct order (names on the tombstones form the name SHRIMPO) should let the monster appear - but only after Apollo gave you the quest.
<img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" /> click with lockpick lvl 5 on the RIGHT graveyard door to enter. I do not know, if Apollo only comes after you have been in Stormfist Castle and survived kidnapping (Iona's pit exit is the exit out of the place you're kidnapped).
Forgot: Apollo comes
after you leave the graveyard. So, your walking direction had to be from north (graveyard) to south, southwest (leaving via gates).
