The Androomba is a rare critter that spawns in Arsenal Labs. It passively rolls back and forth, turning around upon getting close to a block. If a player enters its line of sight, it will panic then start rolling quickly in one direction until hitting a block. Upon hitting a block, the Androomba explodes, leaving behind a flaming destructible scrap pile that deals 10 / 20 Expert Mode / 30 Master Mode damage to the player on contact. The Androomba can also be caught with any type of Bug Net, as long as it hasn't exploded.

Upon placing down the Androomba item, a deactivated Androomba Pal is spawned, facing away from the player. The Androomba Pal can be right clicked by the player with any solution usable by the Clentaminator to change its appearance and activate it. Once activated, it will start moving back and forth while converting blocks around it in a 5-tile wide, 5 tile tall square based on which solution was put into it.

BestiaryBestiary entries

  • Androomba: "One of the most mundane of Draedon’s creations, the directive of Androombas is simply to tidy up his labs and domiciles. He and his scientists could not afford to waste time on menial labor when there was endless research to be done."
  • Androomba Pal: "Reverse-engineered Androombas that have been retrofitted to spread the Steampunker’s solutions rather than clean dust and debris off of floors. They can be used to purify the world– or ruin it further, if one so desires."
