The Bull Helmet is very bulky in appearance. It is yellow and grey and has a heptagon on top of it. It also has two horns like that of a Bull.
- The Bull Helmet increases melee attack power by 50%.
- The Bull Helmet also steadily drains the wearer's health 5 points per second
- The Bull Helmet reduces movement speed by 4%
- Use the Bull Helmet with the Katana for the best results, due to its long range and fast attack speed.
- Try using Boost Pads to attack at blistering speed. But make sure there are no traps around you, or you can be trapped and killed easily.
- You can use the Polearm with the Repeater Crossbow, Crossbow, or Musket for extra damage.
- With the Bull Helmet, the Diamond Polearm will do 80 damage
- Use Angel Wings with the Bull Helmet to decrease the speed of health drain.
- When you are not engaged in melee combat, equip another hat, as the Bull Helmet will drain your health and deplete your Food.
- When you wear the Bull Helmet, don't depend on your ranged weapon. It will not affect the damage of ranged weapons, so maximize on the damage increase and use your main weapon (unless you have Stick, and in that case Bull Helmet will not come in handy that much).
- Use Soldier Helmet or Wooden Shield to reduce the extra damage and to try to outlast your opponent.
- Using a Ranged Weapon can be effective, as with the Bull Helmet, your opponent will not be able to boost their ranged weapon's damage, nor will they be able to attack you if you retreat slowly.

The Bull Helmet was added to MooMoo.io in version 0.62. 0.64 increased the Bull Helmet health drain and damage augmentation. 0.65 increased the Bull Helmet health drain again. In version 0.76, the Bull Helmet sprite was changed to the current one. Somewhere along the line, a glitch was added to the game where the Bull Helmet sometimes did way too much damage. This glitch was fixed in version 0.89. Finally, in version 0.895, the Bull Helmet health drain was increased to 5 a second from 4. The Bull Helmet was also changed to reduce move speed by a currently unknown integer.
