Why is her nose so big in this video?

Waking up beside the burlap sack in the greenhouse, I noticed a bright shaft of morning light cutting across the wooden floorboards. Near the bottom sill of the glass door, a plump garden snail was moving at a slow, determined glide across a dry patch of gravel. Worried it might dry out in the warming sun, I carefully guided a fallen, dewy nasturtium leaf right in front of its path using the tip of my nose. The little traveler slid smoothly onto the cool green surface, and I watched quietly as it nestled into the safe shade.
