There were a set of mobs in Anamnesis Anyder which would spawn additional mobs if not burst down quickly enough - But this didn't matter because the curse of this game is that... To an extent, whilst it is more mechanically complex, the mechanics themselves are just not threatening enough (for a myriad of reasons).
This is the same situation Akadaemia Anyder, with the 2 Bandersnatch that casts an AoE (which you silence/stun) - Again, just not threatening enough, plus they were basically dead before they had a chance. There are probably more, but nothing lives long enough, nor does enough damage for people to bother interacting with it as intended.
