This is a tutorial from Pluralsite. It is a Maya tutorial but I thought it was a good project to "figure out" in Modo. The rig did not transfer well to Modo, but after cleaning up the geometry I used ACS3 to rig the character (including the face). He is going to push down on the jello with his finger and press it down and out. I created a rig for the jello and it works, but I still have to test it with the character.
