Other Info Description: As an axolotl, Vivian is nocturnal and she is usually active from sunset till almost noon. Then she finally has time for slumbering when the sun is overhead. The research laboratory where she works is open 24 hours, so definitely she can work from after dinner until sunrise, often with a siu yeh break for nocturnal lizards like her. The food that she likes the most is, obviously, fish (of course, non-sentient ones) - she can eat hundreds (maybe even up to a thousand) fish each "day" (actually mostly night)! Due to her large appetite, Vivian has to expend much of the energy stored inside her by exercising - she regularly goes to either the gym or the pool to prepare her for annual triathlon events, and this also makes her exceptionally strong - both physically and mentally! Besides, her creativity is beyond how most would imagine, since ideas very frequently pop out from her mind even when she is in her unconscious state during her sleeps!
