Moose Ogres happen when you bury the remains of a moose with those of a ogre. They are angry spirits, they hate mooses and ogres and eat human flesh. Don't do this. Mooses don't like this and even ogres will tell you to be careful with this. Only a vengeful and desperate ogre will deliberately create a Moose Ogre. The only way to appease the cursed moose spirit that animate the Moose Ogre is to kill it to separate the mooses bones from the ogres ones and to bury them separately. Ogres are even willing to team up with humans to hunt down Moose Ogres (but they wont care about appeasing the moose spirit).
