We construct simple solutions of three-dimensional higher spin gravity interacting with matter in which only the scalar and spin-two fields are excited. They preserve Lorentz symmetry and are similar to the four-dimensional solutions constructed by Sezgin and Sundell. The three-dimensional system contains an extra parameter λ which allows us to vary the mass of the scalar. The resulting solutions are interesting for the holographic study of cosmological singularities: they describe the growth of a Coleman-De Luccia bubble in anti-de Sitter space, ending in a big crunch singularity. We study these solutions holographically, finding evidence for their interpretation within a multi-trace deformation which renders the dual field theory unstable. The limit λ → 0 is particularly interesting as it captures effects of a running coupling in a large-N interacting fermion model
