Bulldrome

From Monster Hunter - Wiki on Neoseeker

Well, the Bulldrome is not unlike today's Boars, it is a relatively small monster and is the head honcho of a pack of Bullfangos. It is brown with white bits of fur around its tusks and face. It resembles a pig, hooves, large tusks, and is partial to charging. In fact that's all that it does. It's attack patterns consist of charging at you, charging at you, and charging at you some more. They're easy to evade, dodge and jump out of the way from. All you have to do is slash or fire bullets/arrows at him. While it is not an attack per se, the Bulldrome may shake its body as it turns around after a charge. This shaking will do damage to you if you are close enough and it will also knock you back, leaving you open for a charge.

The Bulldrome is a push over. Seriously. Lots of openings to attack it in, all you have to do is wait until it has charged past you, then all you have to do is attack. It's that simple. Have fun, good luck and Happy Hunting!
