Red is going to be the same way. He's go-go-go! And I'm going to really need to reinforce rate with him.
Are you having trouble with Squiggy blowing by a barrel? Or what exactly is giving you issues?
What I like to do is physically stop before each barrel, at the exact point I would SIT in my seat during a real run. Make sure their hip stays inward toward the barrel when you stop, or even on purpose use your outside heel to push the hip in. (We don't want to create any shouldering in problems.)
Then I will circle each barrel twice, to really instill that turn, and make sure they finish it. If I need to go around it more than twice to get a perfect turn, I will.
More importantly, is my body cues. I am making sure that I SIT in my seat at that precise point every time. Basically, I want it to become a natural instinct for him to STOP when my body sits. This, of course, can be carried throughout your regular riding; not just when schooling on the barrels.
If you need to really reinforce the stop, you can back up a few steps.
Or you can do a counter bend away from the barrel, instead of turning it. (good drill for horses that anticipate)

It is not enough to know how to ride; one must know how to fall.
