Okay, I suggest you get a good feel for AO before you start testing IBL. By the way, that picture is not a light probe. Light probes look something like this:

Go into the Options Window under the Rendering Tab and make sure that AO is turned on and that the sampling is set to something like 25%, and set Mutli-pass to 9 Passes.
Open up your choregraphy, set the Global Ambiance Type to Global Color, and set the color to 50% Grey RGB(128, 128, 128). Set the Ambiance to 100% and Occlusion to 100%. Use only one Sun light that is aming at the ground which will form a 45% angle. This will make the ground white and the shadow of the frog visible.
Also, make sure that your frog has little to no ambiance values.
