Motivated by the successful interpretation of these observed $P_c$ and $P_{ cs}$ states under the meson-baryon molecular picture, we systematically investigate the possible hidden-charm molecular pentaquark states with triple strangeness which is due to the $\Omega_{ c}^{ (*)}\bar{ D}_s^{ (*)}$ interactions. We perform a dynamical calculation of the possible hidden-charm molecular pentaquarks with triple strangeness by the one-boson-exchange model, where the $S$-$D$ wave mixing effect and the coupled channel effect are taken into account in our calculation. Our results suggest that the $\Omega_{ c}\bar D_s^*$ state with $J^P={ 3}/{ 2}^{ -}$ and the $\Omega_{ c}^{ *}\bar D_s^*$ state with $J^P={ 5}/{ 2}^{ -}$ can be recommended as the candidates of the hidden-charm molecular pentaquark with triple strangeness. Furthermore, we discuss the two-body hidden-charm strong decay behaviors of these possible hidden-charm molecular pentaquarks with triple strangeness by adopting the quark-interchange model. These predictions are expected to be tested at the LHCb, which can be as a potential research issue with more accumulated experimental data in near future.
