Fortunately, she made it before anyone saw her indecent display.

Once upon a time in the Underground, the motherly figure named Toriel lived in the Ruins, peacefully taking care of any nascent soul that stumbled upon her door. However, the fateful day came when a child named Frisk chose to journey beyond her warm, comforting home. Worried for Frisk's safety, Toriel set aside her fear of leaving the Ruins and thus, wore her humble robes for the long journey through Snowdin. Little did she know, a blizzard was on its way. The quiet, usually peaceful Snowdin forest had turned into a whirlwind of blinding white snow. The winds started to pick up, howling like lonely wolves in the unforgiving weather. Toriel trudged on; her love for Frisk stronger than the daunting cold. Suddenly, a gust of frigid wind slipped under her robes, cause it to flutter and briefly revealing her bare body beneath. Toriel blushed in embarrassment but quickly secured her robes and continued on her journey. As she neared the small hamlet of Snowdin Town, the winds seemed to intensify, as if challenging her resolve to find Frisk. In a remarkable display of nature's power, one mighty gust charged forward, stripping Toriel of her robes entirely. The wind paraded her simple clothing off into the snowy abyss, leaving a shaken and naked Toriel in its wake. Emotional and red-faced with embarrassment, Toriel, not wanting to be exposed any further, made a swift decision. She made a dash, abandoning the path to Snowdin and instead, setting off towards Waterfall. Despite her humiliation, Toriel's heart was filled with concern for Frisk. She held onto that determination, trusting it to guide her through the treacherous weather and towards the lost child she had grown to care for as if they were her own.
