She grabs her arms and holds them.

Puck and Ash were still locked in combat. The rustling grew louder, accompanied by static and faint, high-pitched laughter. Suddenly, through the trees, hundreds of eyes glowed electric-green in the darkness, surrounding them. Puck and Ash stopped fighting and broke apart, finally aware that something was wrong, but it was too late.

They poured over the ground like a living carpet, appearing from everywhere: small, black-skinned creatures with spindly arms, huge ears, and razor grins that shone blue-white in the darkness. The creatures spotted the girls, and they had no time to react. They swarmed them like angry wasps, crawling up their legs, hurling themselves onto their backs. Claws dug into their skin, their ears filled with loud buzzing and shrieking laughter. The weight of their bodies bore them down, and they fell onto a grasping, wriggling mass. Hundreds of hands lifted them up, like ants carrying a grasshopper, and began to cart the girls away.

(nevermind this one)

She struggles against the creatures angrily, kicking and stabbing at them.

Lise tried getting up, but that proved more difficult than it sounded.

Whenever one was hurt, a dozen more slid in to take their place, bearing them up. The girls never touched the ground. Carried on a buzzing, living mattress, they glided rapidly over the ground and into the waiting darkness.

She eventually tired out, just letting them carry her away. Getting eaten alive by bugs wouldn't be a very nice death, but it would be better than getting killed by her own sister.

She attacks as many as she can, not caring if they hurt her back.

There seems to be an unending amount of these creatures. When Isiea struggled, the claws gripping her would dig into her skin, turning the mattress into a bed of needles. It was uncertain how long they carried them for, but soon the night sky had disappeared, replaced by a ceiling of solid ice. The air grew even colder as the tunnel opened up into a magnificent ice cavern, glistening with a jagged, alien beauty. Huge icicles dripped from the ceiling, some longer than either of the girls were tall and wickedly sharp. It was a tad disturbing passing under those bristling spikes, watching them sparkle like crystal chandeliers. Let's just hope they didn't fall.

Isiea keeps struggling. She doesn't care about being hurt.
