The Butterhawk appears in Agent Corn's final mission, Zero Bark Thirty. In that mission, the player must fly the Butterhawk to provide air support and cover to protect Agent Corn as he delivers a Nuke Juice filled Tactical Cuke to the zombie base. Outside of that mission, she is found settled next to Agent Corn's base.
Full Auto Kernels: A fully automatic, 25mm rotary cannon that fires semi armor-piercing high explosive corn kernels at an incredibly fast rate. Each shot does between 1-10 damage, depending on how far away the enemy was to the shot. The kernels also deal spash damage. It can be fired indefinitely, or at least for an extremely long time.
Corn Cob Cannon: A 105mm cob howitzer that fires depleted-starch armor-piercing cobs. Shots from the cannon travel slower than the Full Auto Kernels, and thus "leading" the shots ahead of a moving target is recommended. The cobs explode in a very large radius and also ignite enemies for extra damage over time. Each shot deals between 15-45 damage, depending on how far away the enemy was to the shot. It also deals 2 damage per second to enemies affected by the burn, which later decays to 1 damage per second. It can fire 3 rockets in quick succession before having to take a short cooldown.
- She appears at several cameo appearances in the game outside the Zero Bark Thirty mission.
- When Butter Barrage or Bigger Better Butter is used, two Butterhawks can be seen flying overhead for a short while in which will drop the butter.
- In the tutorial where the player first plays Sunflower, a Butterhawk will fly to drop two huge corn cobs against a zombie ambush.
- This is because the Butterhawks are also in charge of dropping projectiles such as corn and butter.
- The Corn Cob Cannon could be a reference to the Cob Cannon.
- The Butterhawks that appear when Butter Barrage or Bigger Better Butter is used is much smaller than the versions that appear anywhere else in game, as can be seen in the gallery.
- In the Zero Bark Thirty mission, the Butterhawk orbits around the battleground, similar to the real-life AC-130 gunship.
