Baby mooshroom head is small

This is probably caused by a mistake in animation controller:

"controller.animation.mooshroom.baby": {
      "states": {
        "baby": { // should be "default"
          "parameters": [ "query.is_baby" ],
          "animations": [
            {
              "baby_transform": [
                {
                  "0.0": 0.0,
                  "1.0": 1.0
                }
              ]
            }
          ]
        }
      }
    },

Fixed in beta 1.9.0.5
