Pentaquarks with 
or 
heavy quarks are very much interesting. We analyze the strange pentaquark with or in the coupled-channel quark cluster model. We find bound, resonance and cusp like states.

with quark content 
in light-flavor singlet state is studied in the quark model. This state is analogous to the 
with 
in light-flavor octet, which was observed in LHC in 2015. Considering various combinations of color, spin, and light flavor as internal quantum numbers in , we investigate the mass ordering of the 's by adopting both the one-gluon exchange interaction and the instanton-induced interaction in the quark model. The most stable configuration of is identified to be total spin 1/2 in which the 
is combined to be color octet and spin 1, while the uds cluster is in a color octet state. The other color octet configurations, the total spin 
state with the spin 0, and the state with total spin 
and spin 1, are found as excited states. We also discuss possible decay modes of these hidden charm pentaquarks.
