There actually is not all that much I can tell you about Cera. She does not speak any language I would even recognize. And I am not sure how she even got to TGS, because she is on none of the passenger lists from the flights that came in. Burt mentioned she might be here because of some time travel experiment of his having gone wrong, but surely that must be a joke of his. Scientists sure have a weird sense of humor.
Cera in the Little Pit of Doom
So what I can tell you is that she prefers to head out into the swamp naked. And so that is how she came to the challenge. When she stepped into the pit she kept pushing forward until her legs became trapped. And though she fiercly tried to keep moving the suction of this quicksand made it impossible for her to do so. She really strained herself and put up quite a fight as if this was somehow much more than a fun challenge to her. Still the quicksand held her tight and pulled her deeper which seemed to make her increasingly frustrated. When she was to her shoulders she said a few things that might have been curse words. Tara and I looked at one another, and I realized that since none of us could understand her, we would not know if she had just conceded. Cera said nothing as she struggled on though it was clearly futile. When she was just a face above the surface Tara was standing close by and ready to help her out. Cera looked up at her with pleading eyes and we decided to interpret that as her resignation. After the rescue she gave Tara a tight, long hug.
