My "official" persona's Hyper mode. Of the huge thing on all the forms, here's the discussion of the Fox form:

In fox form, Tluthal is a pretty young vixen with four tails. Her primary fur color is pink, secondary is white, and her hair is a softer shade of brown than her human form's, and approximately waist length. Her eyes are green in this form. Her transformation into a fox indicates hyperness or flirtiness, and is the least serious of all her forms. Anything she says as a fox should be taken with a rather large grain of salt.
