[3.5] Spring Attack + Improved Grab = ?

[Risada]

Let's say I have an animal capable of using Spring Attack and has the Improved Grab ability.

What happens if the animal uses his Improved grab ability while Spring Attacking? Does the grappled creature move with the animal? Nothing happens?

I think there's a general rule that when you want to drag a grappled target along with you, you have to make another grapple check.  So, I'd do that.  If it succeeds, he keeps on springing.  If it fails, then he has to let go or stop.

But that requires you to use an attack action. So I don't think moving them is an option using Spring Attack (unless you're a choker, or you use a Belt of Battle or something to get extra actions).
