Some unrevealed features of megastable chaotic oscillators are investigated. This class of oscillator has a rich dynamical behavior including limit cycle, torus and strange attractor. Also it may have coexisting self-excited and hidden attractors. Such multistable oscillator with coexisting self-excited and hidden attractors is very rare. The relation between megastability and multistability, extreme mutlistability, and hidden attractors is also systematically discussed. Corresponding circuit experiment is also involved to prove this unique oscillation.
