Query: A note on dual giant gravitons in $AdS_{4}\times \mathbb{CP}^{3}$   We study some of the properties of dual giant gravitons - D2-branes wrapped
on an $S^{2}\subset AdS_{4}$ - in type IIA string theory on $AdS_{4}\times
\mathbb{CP}^{3}$. In particular we confirm that the spectrum of small
fluctuations about the giant is both real and independent of the size of the
graviton. We also extend previously developed techniques for attaching open
strings to giants to this D2-brane giant and focus on two particular limits of
the resulting string sigma model: In the pp-wave limit we quantize the string
and compute the spectrum of bosonic excitations while in the semiclassical
limit, we read off the fast string Polyakov action and comment on the
comparison to the Landau-Lifshitz action for the dual open spin chain.
