Drool (OCD) - World of Goo Walkthrough
To get OCD in this level you need to collect at least 24 Goo balls. Both the Green and Water Goo count.
The first thing you need to do is use the Water Goo to build downward. Using 6 Water Goo should be enough to wake the sleeping Green Goo below. Do not use more than 6 otherwise you will not be able to get OCD.
Once you wake the Green Goo start adding them to the right side of the "drool". This will act as a bit of a counterbalance when you start putting the Green Goo on the left. Doing this isn't necessary, but it does help. Once you start building on the left, pay very close attention to how close your structure is to the spikes. Quickly connecting your structure to the pipe can help because the suction will create stability, but taking it slow isn't necessarily a bad idea.
As you start to remove the Green Goo so that they can get sucked in, your structure might move enough to where it touches the spikes so be prepared to quickly remove a Goo if necessary.
*Note* I did this level using only 5 Water Goo by throwing a Water Goo at the Green Goo to shoot them into the air. If the Green Goo bounce close enough to the structure they will waken. It's actually possible to complete this level using only 3 Water Goo, but it's very difficult getting the Green Goo up that high without any hitting the spikes on the left.
