The morph they were going to use would be yet another new one: bats. They would be the only ones who could find their way through the pitch-dark room, dodging the sensor-wires while staying off of the ground so they wouldn't set off the pressure sensors there, either. Marco and the rest of them had clearly been expecting, or at least hoping, that they would have the chance to test the morph out, to get used to it before they needed to use it.
Tommy had wanted that, sure, but he'd long since learned not to expect to have the time for things like that.
"There's a problem," Erek reported, once all of them had demorphed and arrayed themselves around him. "The Yeerks are putting in a brand new security system on top of the existing systems. I don't think it's active, but I haven't been able to find out what it is yet."
(It's fine,) Tobias said, looking down at them from his place up in the rafters of the barn. (We can wait a few weeks for you to get the details.)
Erek shook his head. "The crystal is already so well protected that any new system might put it beyond our reach for good. And don't forget: the Yeerks are racing to use the crystal to create a computer system so powerful that it can take over every other computer on Earth. They're not there yet, but waiting longer won't help us."
"Great," Marco grumbled, shaking his head. "No planning, no preparation, we just dive right in and hope for the best."
"We've done it before," Tommy said, though he wasn't particularly pleased about it, either.
Using the bat's senses to actually navigate wasn't something that would be easy to learn on the spot, but under the circumstances they were just going to need to adapt. The same way he and the rest of the other Animorphs had had to do so many other times before.
