The Star Swallower Containment Unit is a craftable Pre-Hardmode summon weapon. It summons a grounded bio-mechanical frog minion that jumps around the player. When an enemy is nearby, it fires gravity-affected acid droplets that inflict the Irradiated debuff. It does not directly deal contact damage.

The weapon consumes 0.08 units of charge per use and has a maximum charge of 50.

Its best modifier is Ruthless. The Mythical modifier provides the widest array of stat bonuses, but these primarily affect the initial summon rather than the resulting minion. Additionally, minions cannot deal critical hits. The only lasting advantage a Mythical Star Swallower Containment Unit has over a Ruthless one is knockback.



The Star Swallower Containment Unit cannot be crafted until the Schematic from the Sunken Sea Bio-center Lab is found. If the requirement has not been met, two lines of tooltip are added at the bottom of the item:
You don't have sufficient knowledge to create this yet
A specific schematic must be deciphered first

  • The Star Swallower buff tooltip is a reference to the "mmmm myes pet froge" meme.
  • The description line "strangely popular with humans" is likely a nod to the fact that many people find frogs cute and/or funny, despite them being conventionally 'ugly' by general standards
  • The frog minion is named 'Pet Froge' in the files.
