  Two types of excited oscillons are investigated. We first focus on spherical
symmetry and find that there are a tower of spherical oscillons with higher
energies. Despite having multiple approximate "nodes" in their energy density
profiles, these oscillons are long-lived. We find that during the lifetime of a
highly excited oscillon it will cascade down all the lower energy levels before
its disintegration. We also point out the existence of excited oscillons with
higher approximate multipoles, which generally have shorter lifespans than the
spherical ones. Apart from performing nonlinear simulations with absorbing
boundary conditions, we also apply a perturbative method to analyze some
features of these excited oscillons.
