  We address a simple model allowing the existence of domain walls with
orientational moduli localized on them. Within this model, we discuss an
analytic solution and explore it in the context of previously known results. We
discuss the existence of one-dimensional domain walls localized on
two-dimensional ones, and construct the corresponding effective action. In the
low-energy limit, which is the $\mathbb{O}(3)$ sigma-model, we discuss the
existence of skyrmions localized on domain walls, and provide a solution for a
skyrmion configuration, based on an analogy with instantons. We perform
symmetry analysis of the initial model and of the low-energy theory on the
domain wall world volume.
