Does an adult/elder oblex have to use an action or bonus action to retract a simulacrum? It takes a bonus action to extrude one, but it doesn’t say how it retracts one. Hmm. I didn't work on the oblex, so I'm not comfortable diving into that one on an intent standpoint.
As a DM, I'd have the oblex able to dissolve a simulacrum as it wishes, basically at any time (similar to ceasing concentration).
