Butt Stallion

Butt Stallion is Handsome Jack's diamond pony. She initially is only heard during the beginning of the main story, but makes a physical appearance as a main character in Tiny Tina's Assault on Dragon Keep.

Overview
Butt Stallion is first introduced on the Southern Shelf by Jack, during the mission Best Minion Ever. He mentions he has bought a pony made out of diamonds in an ECHO message to the player. Jack messages the player again telling them that he was trying to come up with a name for the pony he just bought. He says at first he was going to call it "Piss-For-Brains" in honor of the Vault Hunter, but changes it to 'Butt Stallion.' Later he clarifies that the diamond pony he bought is not a statue or a metaphor, but a real pony made out of diamonds. Butt Stallion last appearance in the main story is in an ECHO message to the player from Handsome Jack in Three Horns - Divide, when Butt Stallion whinnies in the background.

Tiny Tina's Assault on Dragon Keep
Butt Stallion makes her physical appearance at the end of the final mission. It is revealed that she is the queen that the player has been seeking and with the defeat of the Handsome Sorcerer, Butt Stallion restores light and order to the land. After the final mission, she can be found in Flamerock Refuge with Roland. Feeding her 5 Eridium will cause her to poop a single piece of loot. This can be done as many times as the player wants. Every time Butt Stallion poops out loot, there is a small chance she'll do a special movement and then poop a special weapon. These weapons are purple quality but have unique skins and unique names based around gemstones. There is also a chance for Butt Stallion to vomit instead of pooping, which mostly results in a blue weapon.
