  Growth-fragmentation processes describe the evolution of systems in which
cells grow slowly and fragment suddenly. Despite originating as a way to
describe biological phenomena, they have recently been found to describe the
lengths of certain curves in statistical physics models. In this note, we
describe a new growth-fragmentation process connected to random planar maps
with faces of large degree, having as a key ingredient the ricocheted stable
process recently discovered by Budd. The process has applications to the
excursions of planar Brownian motion and Liouville quantum gravity.
