DERRICK: Just adding a couple finishing touches.
Well I worked through the night.
I added these hinges.
I articulated, so cut this design in half,
and made it so she can actually bend her leg.
Really thinking it's going to be great for her.
Finito!
This is a huge moment.
We're going to help two animals with one device.
Kind of unheard of.
I need this to work for Yusi and Zara.
What's up, guys?
What's up, Yusi?
Look.
You want to see your new leg?
JAMIE: She says, put it on me.
It's the time.
Let's do it.
Get you in there.
You're getting used to this drill, aren't you.
There you go.
One more strap.
So I think we're ready.
I think we can take her out let's do it.
I'm excited.
Here comes Zara.
JAMIE: Come on.
DERRICK: Mama, come get your girl.
JAMIE: Come on, sweetheart.
DERRICK: Come get your girl.
JAMIE: Come on.
There you go.
DERRICK: There's a step.
JAMIE: Come on.
DERRICK: There's a step.
Yay!
JAMIE: OK.
DERRICK: Let's look at it.
JAMIE: Come on.
Let's see.
You can bend.
JAMIE: Yeah.
DERRICK: You can bend.
[clicks tongue]
Yeah.
Looks like it's a little high.
So we're just going to drop her down a little bit
with this kind of safety foot.
So let's give that a try.
[clicks tongue]
Let's see.
JAMIE: Come on, baby.
DERRICK: Yeah?
JAMIE: You can walk now.
Come on.
DERRICK: You can do it.
Hi.
Can I get you to walk?
We can get her to walk.
JAMIE: Come on.
[whistles]
DERRICK: Come on.
JAMIE: You can do it.
Come on.
[clicks tongue]
Why?
DERRICK: I don't know.
What do you want, buddy?
You in there?

Yusi, come on.
[horse grunts]

JAMIE: No, good girl.
Hi, Zara.
