  This is a continuation of developing mutation theory in exact WKB analysis
using the framework of cluster algebras. Here we study the Schrodinger equation
on a compact Riemann surface with turning points of simple-pole type. We show
that the orbifold triangulations by Felikson, Shapiro, and Tumarkin provide a
natural framework of describing the mutation of Stokes graphs, where simple
poles correspond to orbifold points. We then show that under the mutation of
Stokes graphs around simple poles the Voros symbols mutate as the variables of
generalized cluster algebras introduced by Chekhov and Shapiro.
