She has a fierce interest for Dutch history and culture, and she especially seems to like the elements of Dutch history that relate to colonialism and the Dutch East India Company (VOC).

All of her interests revolve around Dutch culture, bolstered by her patriotism towards anything Dutch Mymy has warm coloured skin, upturned almond shaped eyes, freckles, dyed ginger hair and has blue eyes from her colour changing contact lenses. Her clothing is that of regular school uniform, blue skirt, white polo shirt and an orange tie.

These colours are similar to those of a Springbok, the animal used in the emblem of the rugby team she supports.
