At your current diminutive size, opening your mother’s lips proves a little difficult. However, the gigantic woman’s nostrils remain accessible as she rests on her side! You make your way into the nasal cavity, taking extra care not to wake her in the process.
Per your expectations, it’s fairly dark within the tunnel of your mom’s nose. Thanks to the light of the outside world, however, you’re able to see tiny blobs of sticky mucus coating the nose hairs that line the walls of this inner realm…along with slightly larger blobs on the “floor”. You might get stuck in the stuff if you get too close - better to just move along.
You can’t help but feel amazed at being literally inside another person’s body - a shame you didn’t bring along a camera to photograph your adventure. But at least your smartphone had shrunken with you! That ring you’d invented sure works wonders. Putting on your phone’s flashlight, you snap a few photos of the interior of your mother’s nose…although, she might worry for your safety if she ever found out you were exploring her innards.
Soon, you reach the end of the nasal passage and are faced with numerous options for your next destination. Maybe you could check out your mom’s lungs, or perhaps get a peek at her brain?
