The Dink Network

reDink v0.04 (A modified verson of Dink) has a way to do this.) Otherwise you could put something like this in the monster's his procedure:
int &junk = get_sprite_with_this_brain(5, 1); if (&junk > 0) { sp_seq(&junk, 166); sp_brain(&junk, 7); }

But if other sprites with brain 5 (play seg, draw last frame to background), such blood spurts from other monsters, are around, that might not work.
