She peeks a little harder.
She whispers to the others, "This isn't the same kind. Trouble looks okay."
Bella follows, clutching her sister's hand, maybe for balance.
And then everyone gets a picture of -
A greenish-gray slug, large for a slug but easily pocket-sized.
<They need hosts. They enter through the ear. Without them they are almost powerless, but when they become Controllers - when they wrap around a host brain and take over their thoughts and actions - they are dangerous. They prefer cooperation. They do not need it. We had hoped to stop them, but soon they will be here to obliterate all trace of me and my ship.>
"Talk about pod people," mutters Trouble. "So what are you warning us for? How do we know who to spill to? A bunch of kids aren't gonna stop an alien invasion by themselves."
<I...> The alien turns all four eyes towards Trouble again, even as the others approach. <I may be able to give you some small advantage. It may help. If you go into my ship you will find a blue box, very plain.>
"How many Yeerks are there? How do you understand English? How can we identify Controllers if we're not sure? Can we get Yeerks out of people? What about the other aliens with all the blades? Are there more of you coming to help? What powers can you give us?"
<There are many millions of Yeerks. And they can breed quickly when there are hosts for them. On this planet - I do not know, but tens of thousands, at least. Controllers can mimic their hosts perfectly if they wish, but Yeerks must leave their hosts once every -> He pauses to make some kind of calculation. <Three Earth days, to go into a Yeerk pool and feed on Kandrona rays, from their home sun or an engineered duplicate. Longer than that and they begin to starve.> He pauses again, main eyes shutting briefly, perhaps in pain. <If you have seen a bladed alien that was not my kind it was probably a Hork-Bajir. They are peaceful of themselves, but their world fell years ago and are now all infested by Yeerks. More Andalites like myself may come to help here but I know not when. And -> He holds his hand out for the blue box.
<I can, if you are willing -> His stalk eyes crane upward, scan the sky. <I can give you the power to morph. Any animal you can touch and concentrate on will be yours to become. The Yeerks do not have this technology. There are limits, but it may help you.>
"If you can do that why don't you turn into something that isn't burned - does that not work? -"
<It does work. I do not have the strength to morph in this condition; I am dying. Will you take the power?>
<Each of you, place one of your hands on one of the sides of the box. Do not be afraid.>
<You must never -> The Andalite's stalk eyes still in their search. <The Yeerks are coming; we are running out of time. Never remain in morph for more than - two hours. Never. If you do you will be trapped, unable to demorph, in the form you overstay. Now run. The Yeerks -> One of his stalk eyes twitches. <Visser Three is with them. They must not catch you.>
"I can't - run," Bella murmurs, taking the box and handing it to Andi, "I fall -"
<You cannot be here when they land - they are already narrowing their search - acquire one of your friends, if they can run where you cannot,> suggests the Andalite, collapsing ungracefully, legs folded under himself.
