Nini Doll is a very determined mouse girl. She is determined to be the strongest she can be, the best she can be, and the mouse that Neek calls his girlfriend.

Nini is highly competitive but not petty or cruel, though she not above rubbing her rivals faces in her muscular and brilliantly honed body, metaphorically. Avida has he hands full with the huge muse girl trying to win over Neek first.

Nini likes a good challenge be it more weight or winning over a boy.
