You had some time to think, and thought that having 4 cow legs would be a lot easier for since you were able to move around easily, and it made your new udder less heavy whenever you could feel it filling up. However, you couldn't stand looking at the cow face, so you decided to get rid of it, while keeping the lower half.
So, with that in mind, you tell Gary that you wanted to keep the tauric package, while at the same time return to your humanoid upper-half, while doing so as the milk tubes come off of your udder teats, and he agrees with your choice. "Please note, after this next injection, there's an extra side effect," Gary explains. "You'll see after you've taken it, so just relax while it all begins." You do what Gary said, and relax, as a needle pokes into your arm, while you feel fur shedding off you.
