We discuss observational consequences of the curvaton scenario implemented in the context of the simplest model of chaotic inflation in supergravity. The non-Gaussianity parameter $\f_{NL}$ in this scenario is very sensitive to the choice of the model parameters; it can be either very small or very large, and it can take different values in different parts of the universe. Under certain conditions, this parameter can take values in the observationally interesting range from $O(10)$ to $O(100)$.
