Naedocyte Breeders serve as the motherships of the Naedocyte Collective, and provide a constant mental link between any nearby Naedocytes. They are known to travel great distances back and forth to check up on their myriad egg deposits, and display a level of solemn tenderness that's almost unheard of on Hoxxes. Still, their constant depositing of fresh egg clutches pose a direct threat to the operations of DRG, and any Naedocyte Breeder should be exterminated on sight. Plus - despite appearances, they are fairly delicious with a spritz of lemon.
— Miner's Manual Description
The Naedocyte Roe is a special creature, created only by Naedocyte Breeders. It will never appear if a Breeder is not present in a level.
The Roe is technically not an enemy, more of an entity which can be destroyed. It has no attacks of any kind, nor can it even move once it is spawned. It is periodically created by Breeders, being dropped onto the ground whenever the Breeder's "mouth" is open. The Roe will not take any falling damage when dropped and is capable of stopping all momentum as soon as it hits the ground.
Roe sacks will stay on the ground where they are dropped, pulsating and writhing in place. As time passes their coloration will change from blue to a pinkish-purple, until it eventually bursts open and spawns a cluster of Naedocyte Hatchlings. The Roe as an entity will cease to exist once the Hatchlings are birthed.
If a Roe is "killed" before it can hatch, no Hatchlings will be spawned on its demise.
