We construct examples of renormalizable Carrollian theories with finite effective central charge and non-trivial dynamics. These include critical points that are not scale-invariant but rather exhibit hyperscaling violation. All of our examples are mildly non-Lagrangian, in that they arise from suitable N→ 0 limits of Carrollian theories with N-component fields, including limits of Carrollian vector models and non-abelian gauge theories. We discuss implications for flat space holography, highlighting challenges in realizing Carrollian duals to gravitational theories.
