Motor oil in the water!

I spent most of my day today working on levels in Scratch, so I don't really have many things to post here. However, since I'm getting close to one of the oases (yes it's not "oasises") where the denizens of the city used to get their water from, I created a little motor which goes at the ends of the pipes to push the water through the pipes. Here it is:

It has a pretty simple animation, but, you know, I was lazy, and watcha gonna do, right? I'll get to work on the actual oasis tomorrow, should be fun :). Oh, and you can't swim, so you basically sink to the bottom. Bummer. Here's a screenshot of some more pipes.
