  We consider giant gravitons in the maximally supersymmetric type IIB
plane-wave, in the presence of a constant NSNS B-field background. We show that
in response to the background B-field the giant graviton would take the shape
of a deformed three-sphere, the size and shape of which depend on the B-field,
and that the giant becomes classically unstable once the B-field is larger than
a critical value B_{cr}. In particular, for the B-field which is
(anti-)self-dual under the SO(4) isometry of the original giant S^3, the closed
string metric is that of a round S^3, while the open string metric is a
squashed three-sphere. The squashed giant can be interpreted as a bound state
of a spherical three-brane and circular D-strings. We work out the spectrum of
geometric fluctuations of the squashed giant and study its stability. We also
comment on the gauge theory which lives on the brane (which is generically a
noncommutative theory) and a possible dual gauge theory description of the
deformed giant.
