  Natural theories of the weak scale often include fermionic partners of the
top quark. If the electroweak symmetry breaking sector contains scalars beyond
a single Higgs doublet, then top partners can have sizable branching ratios to
these extended Higgs sector states. In fact, top partner decays may provide the
most promising discovery mode for such scalars, especially given the large
backgrounds to direct and associated production. In this paper, we present a
search strategy for top partner decays to a charged Higgs boson and a bottom
quark, focusing on the case where the charged Higgs dominantly decays to
third-generation quarks to yield a multi-b final state. We also discuss ways to
extend this search to exotic neutral scalars decaying to bottom quark pairs.
