Bullbo

Bullbos are recurring boar-like creatures in. They are frequently used as mounts by Bulblins.

Twilight Princess
Bullbos in are extremely tough and can only be killed by running them off a cliff or repeatedly attacking them with a sword. An easy way to halt them while riding Epona is to shoot them with a Bomb Arrow which will make quick work of them. They are nearly impossible to stop once provoked. A rider must either wait for them to calm down on their own, or guide them into a solid wall.

Bullbos are usually ridden by Bulblins. There are two Bulblins to each Bullbo, a rider and an archer. If the rider is knocked off the Bullbo, the Bullbo will begin to rampage, dislodging the remaining Bulblin from its back. The beast will continue to charge until it crashes into a solid structure or runs off a cliff.

After knocking the Bulblins off, Bullbos can be ridden in a similar way to Epona. However, the brutish creatures are far less intelligent than Link's horse. They do not appear to have the sense to stop before running into solid objects or even off cliffs. Link cannot quickly dismount them the same way he can while riding Epona, and he also cannot use items while riding them. A Bullbo's charge is different than Epona's as well. Interestingly, when a Bullbo is charging, it gallops so violently that Link can only cling to the reins. Charging Bullbos cannot jump and are more difficult to steer than Epona, although the charge lasts longer and is faster than Epona's. Just before sprinting, a Bullbo will rear onto its hind legs and roar similar to a horse. When they are at top speed, they are impossible to stop and only after a short length of time or when rammed into a wall will they halt. Finally, when sprinting, Bullbos can smash wooden fences and Bulblin towers, which are otherwise almost indestructible (Bulblin towers can also be broken with the use of the Ball and Chain). When spurred or attacked with a weapon, Bullbos will run off and eventually fall over but will get up to be ridden again. A notable Bullbo is Lord Bullbo, the massive mount of King Bulblin, who cannot be ridden by Link as normal Bullbos can.

Bullbos are also used for meat, as seen in the Gerudo Desert. A dead, hairless Bullbo can be found tied to a spit over a fire. If Link slashes the roast Bullbo, recovery Hearts will appear, and repeated attacks will cause it to burst, revealing a Piece of Heart.

Spirit Tracks
Bullbos make a similar appearance in, where they can be found in areas of the Forest Realm, Snow Realm and Fire Realm, this time Bullbos are enemies without riders who charge at the spirit train. Some Bullbos are once again mounted by Bulblins who either fire Bomb Arrows. They can be defeated with two shots from the cannon.

Etymology
"Bullbo" may be a portmanteau of "bull" (referring to a large adult male mammal), and a contraction of the word "boar" )forming bo).
