This here hog can "clear the savanna after every meal", it will however, be quite a large meal indeed. Also breed them so when you have a baby you can scream "WHEN HE WAS A YOUNG WARTHOG!"

They will use their healing move in the wild and this actually makes taming these burly beasts much easier preventing accidental deaths and making them hungry leading to a 30 second tame

Found in ice biome on center island extinction and raganok are a endgame tame since these guys are 100000% needed for bosses (especially the dragon) but be warned I've seen them hunt in packs lately so be careful I hope this help <3

Use Traq arrows to knock because it will take more damage and forces it to heal itself and as a result draining more food. This will drastically decrease how long it takes to tame.
