Results for the first measurement of the inclusive branching and CP asymmetry of the charmless 3-body decay B⁺ → K⁺π⁰π⁰ are presented. The analysis uses a data sample with an integrated luminosity of 429.0 fb^-1, recorded by the BABAR detector at the PEP-II asymmetric B Factory. This sample corresponds to 470.9 ±} 2.8 million B$$\bar{B}$$ pairs. Measurements of the branching fractions (B) and CP asymmetries (A_CP) of some of the intermediate resonances in the K⁺π⁰π⁰ Dalitz plot are also presented.
