in front of them. Out of it comes a dying alien, an andalite
called Elfangor-Sirinial-Shamtul. He tells about a disaster
threatening the universe, the yeerks, the parasites of the universe:
The yeerks are grey slugs, that crawl through the ear and take over
the brains controlling their hostbodys all functions from eating,
sleeping and expressions to reading their hostbodys thoughts and memories. And they are
invading Earth.
The youngsters have a frightening mission now. They have to try to save humans
from the yeerk invasion. To help them in the battle the andalite
gives them the power to morph, or to "acquire" an animals DNA and to turn into that animal.
"Humankind is threatened by a great danger. Nobody on Earth is safe. Jake,
Rachel, Marco, Tobias and Cassie are the only humans, who know about
it. They can't close their eyes from the truth, because only they can save
the Earth. They are just normal kids, but they have a very unnormal ability. They
can turn into animals. They are the Animorphs."
