We analyze the thermodynamical properties of the regular st atic and spherically symmetric black hole interior model presented by Mboyne and Kazanas. Equations for the thermodynamical quantities valid for an a rbitrary density pro- file are deduced, and from them we show that the model is thermo dynamically unstable. Evidence is also presented pointing to its dynami cal instability. The gravitational entropy of this solution based on the Weyl cur vature conjecture is calculated, following the recipe given by Rudjord, Gr ∅ n and Sigbj ∅ rn, and it isshown to have the expected behavior
