In my own opinion, Hoppi is completely fine with her normal mechanic; you have an audio lure to delay her arrival. The real problem with Hoppi is her agro mechanic being the most punishing of all the other dolls as of currently.
For Teddi, just don't watch her and you're pretty much set.
Catti? she only ever deals 10% dmg to your door power if she hits without you watching her, so she's a breeze too.
Hoppi punishes you for literally dealing with her the way you should; stalling Hoppi is all you can really do to prevent her agro mechanic. I myself made a simple guide on how to delay Hoppi for others.
