Mystery polyps showed up overnight!

Not quite sure what these guys are, they look like tiny mushrooms. Short stalk, growing in clusters, flat disc like head with what appears to be a central mouth on top.

Look like some sort of small mushroom species, pretty cool

Looks like a type of Caulerpa Macroalgae, either Racemosa or Peltata

Didn't notice the green tint to them. This seems right

UPDATE
I have confirmed the species to be "caulerpa nummularia" which is especially quick growing and a PITA to get rid of [emoji52]
I have since manually removed as much as possible and transferred to the refugium where I hope to keep it contained.
