  In this talk I look into three different topics, addressing first the
possibility that the $\Theta^+$ is a bound state of $K \pi N$, exploiting the
results of this study to find out the contribution of two meson and one baryon
components in the baryon antidecuplet and in the third place I present results
on a new resonant exotic baryonic state which appears as dynamically generated
by the Weinberg Tomozawa $\Delta K$ interaction.
