In this talk I look into three different topics, addressing first a method to determine the quantum numbers of the +, then exploiting the possibility that the + is a bound state of K N and in the third place I present results on a new resonant exotic baryonic state which appears as dynamically generated by the Weinberg Tomozawa K interaction.
