Quasi-periodic pulsations (QPPs) are a common feature of solar flares that are observed in
many different wavelengths. Although QPPs appear not to be as abundant in white light Kepler
flare light curves as they are in solar flares, albeit in different wavelengths the structure of the
pulsations are strikingly similar, hinting that the same underlying processes govern both solar
and stellar flares. Here we consider a special case, observed on KIC9655129, which shows
evidence of multiple periodicities. We speculate that the presence of multiple periodicities is a
good indication that the QPPs were caused by magnetohydrodynamic oscillations, further
strengthening the case that the physical processes in operation during stellar flares are at least
analogous to those in solar flares.
