Warthog

Warthogs are found in Howling Sands and have been seen near Meerkats. They seem to be decently large in size, about a block or two high, and have dark brown fur and two large tusks.

Although not much is known about a warthog's behavior, we can only assume that they are passive due to a video clip we see of a meerkat and a warthog walking friendly together, (which is a Lion King reference) and they are in the Hog family, which is also supposedly a passive mob that is found in Emerald Grove.
