corals...bubbling...?

[squishifishi]

one of my hitchhicker nems and a mushroom are bubbling at the base. there are just these spots where the skin on the neck is really thin and poofed out like a bubble. Imaggune how carmel looks when youare boiling it, i guess their bases look kind of like that. i don't really know how to describe this but does this sound like something you've seen before? what does this mean, or what are they doing?
thank you so much!

ok, well looking at it this morning, i think mabey it was making a baby?

each of the 2 big bubbles at the base now have flattened, open, tops, and a the center there is a darker, pinched looking spot like a mouth. the other bubbles have alltogether dissapeared. so, correct meif i'm wrong, but i guess it just decided it was time for some moore heads!
thanks!

mushrooms walk a lot. when they walk they leave little pieces of their foot behind that end up creating a new shroom. sounds like what happened with yours
