We point out that nonleptonic B decays driven by b{yields}ccs should provide a favorable environment for the production of hidden charm diquark-antidiquark bound states that have been suggested to explain the resonances with masses around 4 GeV recently observed by BABAR and BELLE. Studying their relative abundances in nonleptonic B decays can teach us novel lessons about their structure and the strong interactions. Through their decay into {psi} they can provide a natural explanation of the excess of B{yields}{psi}X observed for p{sub {psi}}<1 GeV. Other phenomenological consequences are mentioned as well.
