  While the presence of a light stop is increasingly disfavored by the
experimental limits set on R-parity conserving scenarios, the naturalness of
supersymmetry could still be safely concealed in the more challenging final
states predicted by the existence of non-null R-parity violating couplings.
Although R-parity violating signatures are extensively looked for at the Large
Hadron Collider, these searches always assume 100\% branching ratios for the
direct decays of supersymmetric particles into Standard Model ones. In this
paper we scrutinize the implications of relaxing this assumption by focusing on
one motivated scenario where the lightest stop is heavier than a chargino and a
neutralino. Considering a class of R-parity baryon number violating couplings,
we show on general grounds that while the direct decay of the stop into
Standard Model particles is dominant for large values of these couplings,
smaller values give rise, instead, to the dominance of a plethora of longer
decay chains and richer final states that have not yet been analyzed at the
LHC, thus weakening the impact of the present experimental stop mass limits. We
characterize the case for R-parity baryon number violating couplings in the
$10^{-7} - 10^{-1}$ range, in two different benchmark points scenarios within
the model-independent setting of the low-energy phenomenological Minimal
Supersymmetric Standard Model. We identify the different relevant experimental
signatures, estimate the corresponding proton--proton cross sections at
$\sqrt{s}=14$ TeV and discuss signal versus background issues.
