Crafty monsters those are..." - ―Commander dialogue on Wave 11 (Headache Headquarters)

Description
The Png Bot2 was an enemy that appeared in Headache Headquarters, replacing the Breaker2. Currently, it only appears when the Brain Rot modifier is activated in Sandbox mode, replacing every Breaker2 modern variant, or with its Logbook. It has a high amount of health and a rather fast speed. Additionally, it spawns a Png Bot upon death, which has less health but was faster.
Appearance
The Png Bot2 is a two-dimensional enemy that had multiple appearances. All of them are various images of cats, some of them being memes and other images of the developer's cats.
Headache Headquarters Strategy
As this enemy only appears through Sandbox mode, no strategy section is made for its current version. Instead, a strategy section for the one that appeared without Sandbox mode in Headache Headquarters is listed instead.
- Strong early-game towers like the Brawler, Golden Scout or Golden Crook Boss are very effective here.
- Towers with crowd control capabilities, like the Electroshocker or Mortar, can also be useful here.
- Stalling towers, like the Cryomancer, Freezer or Frost Blaster, can also be useful, due to the Png Bot2's speed.
- High DPS towers like the Minigunner and Accelerator can be useful against this.
- The Commander and DJ Booth can be useful at boosting the firerate and range of your towers respectively.
