Yeah, unfortunately, it's pieces of excrement like that which you find are not able to be flushed down the HC toilet. They are just floaters in the bowl that hang around with the cockroaches which are equally difficult to flush. HC is infested with them and are unfortunately a protected species here as they generate income/clicks.

There's plenty of them here on the AVZ forum. There's never just one cockroach. They know who they are and some even have previously good reputations which they are quickly trashing.
