We present high spatial resolution HST imaging of the LMC compact H II region N159-5. This high excitation blob is revealed to be a "papillon" or butterfly-shaped ionized nebula with the "wings" separated by (0.6 pc). Two subarcsecond features resembling a "smoke ring" and a "globule" are detected in the wings, the origin of which is briefly discussed. N159-5 may represent a new type of H II region in the Magellanic Clouds overlooked so far because of insufficient spatial resolution. Our images also show a strikingly turbulent medium around the Papillon in the giant H II region N 159, which manifests itself by a large number of subarcsecond filaments, arcs, ridges, and fronts carved in the ionized gas by the stellar winds from massive stars in the N 159 complex.
