I haven't tested this elsewhere or with other creatures, but when fighting Mouboo next to Oscar/the Fruit Store, you can die, respawn, attack nearest target (Mouboo) via left CTRL, and they won't fight back. You can kill them this way and still get experience and their drops.

Edit: Map 011-1, around (103, 34).

yerp, there is a patch for this in the next release.
