  Light top partners are the prime sign of naturalness in composite Higgs
models. We explore here the possibility of non-standard top partner
phenomenology. We show that even in the simplest extension of the minimal
composite Higgs model, featuring an extra singlet pseudo Nambu-Goldstone boson,
the branching ratios of the top partners into standard channels can be
significantly altered, with no substantial change in the generated Higgs
potential. Together with the variety of possible final states from the decay of
the pseudo-scalar singlet, this motivates more extensive analyses in the search
for the top partners.
