Tremble Lizards

When one of the tremble lizards disables the energy barrier, a bunch of them heads towards the research outpost station to kill everyone. But after Mariner recklessly gets all the tremble lizards back behind the fence, Mariner fails to notice that she has a tremble lizard on her back and she accidentally brings it inside the station, which ends up pouncing on one of the outpost scientists.
