Bouncy Seeds: Bitter Dill's main form of attack, he spits out seeds that bounce off the walls and floor. Knocks away zombies that are hit by it.
Goop Spin: If a zombie gets too close, Bitter Dill will spin around and create a cloud of Grody Goop around him. Much like Bouncy Seeds, knocks the player back.
Grody Goop: Bitter Dill will sometimes spit out a Grody Goop, similar to Chomper. This slows zombies, and makes them unable to use abilities, and deals toxic damage.
Bitter Dill can be a very annoying opponent; his tendency to bounce all over the place and his relatively small hitbox (for bosses) makes him difficult to hit.
To make matters worse, his main attack will knock you backwards, possibly off a cliff or into some other obstacle, or could just mess up your aim and prevent you from landing any hits on him. Plus, Bitter Dill can spit out pools of goop (similar to the Chomper's Grody Goop) that can prevent you from moving or using your abilities. As such, to defeat him, it is recommended to have at least two Zombies teaming up against him so one can attack while the other is being thrown backwards.
Try not to play as Super Brainz, as Bitter Dill's knockback will prevent you from being able to deal any melee damage. All-Star is a good choice for one, as his high health allows him to take the hits while the other Zombie attacks. His Dummy Shield can also help him survive longer.
Bitter Dill's elite wave can be annoying, but its still a bit easier than most elite waves.
During the wave, he spawns Weeds, Wildflowers, Corns, and Cacti after the players.
When Bitter Dill loses a fourth of his health, he will become briney, and will be invincible. He will drop a mint that somebody has to pick up and take to a soda trap. When briney, Bitter Dill doesn't shoot Grody Goop or Bouncy Seeds, he only chases after players and does Goop Spin. Once Bitter Dill is hit with the soda trap, he will become attackable again. Players have 10 minutes to defeat Bitter Dill. When the timer runs out, its game over.
