N2 - If a narrow Θ+ pentaquark exists, it is likely that a uds̄-ud triquark-diquark configuration is a significant component of its wave function. If so, the mechanism responsible for the binding of a triquark and a diquark is also likely to bind the triquark to an s̄ antiquark. We discuss the expected properties of such a uds̄-s̄ tetraquark meson. In particular, we point out that for a 0+ isoscalar uds̄s̄ meson the lowest allowed decay mode is a four-body KKππ channel with a very small phase space and a distinctive experimental signature.
