  In this note, we point out that in the eternal inflation driven by the
metastable vacua of the landscape, it might be possible that some large and
local quantum fluctuations with the null energy condition violation can stride
over the barriers between different vacua and straightly create some islands
with radiation and matter in new vacua. Then these thermalized islands will
evolve with the standard cosmology. We show that such islands may be consistent
with our observable universe, while has some distinctly observable signals,
which may be tested in coming observations.
