For OCD begin by pulling all the goo balls off the existing structure they are weighing the ladder down, so it takes more goo balls to reach the pipe. This simple strategy, however, will not allow you to collect the 22 goo balls needed for OCD. Once they have been woken up, build a tower on the top of the structure to reach the pipe. The first step is to build a ladder down to the sleeping goos. The pipe is located above the structure and a bunch of sleeping goos are located at the bottom of the stage. Use the goos you have remaining to build up to the pipe, making sure that you have at least 8 goos to complete the level. When you reach the other side of the ravine, the sleeping goos will wake up. You may have to build up a bit if the bridge sags too much. Unfortunately, because your structure isn't completely rigid, the bridge will begin to sag as you build it. In order to reach the pipe, you must build a bridge across the chasm. The pipe is located on the opposite side of a ravine with sleeping goos directly underneath it. To tell if you are placing the goo high enough, the white guideline should be either entirely or almost invisible place the goo right at the border. Just make sure to place each goo as high as you can so that the third goo can be pulled in by the suction of the pipe. In order to get the OCD, you must only use three goos to complete the tower. All you have to do is build a tower to reach the pipe and the remaining goos will be sucked in. The pipe is located directly above the starting structure.
