It's slow going, moving without jostling her belly too much, especially through such a winding and twisting path of interconnected and tangled branches and roots.
Twice she thinks she's on solid ground only to reach a turn and realize she was on yet another tree branch the whole time.
She isn't worried about getting lost. She's moving so slowly that however long it takes for her to lay her seeds, once she does and she can fly through the canopy at over a hundred miles per hour again, backtracking days of walking would only take minutes.
What's more, more and more knowledge keeps bubbling in her brain. She can just look at a plant and already know what it is. She doesn't have to wonder if something is safe to touch, to brush against with her bare skin. Not that there's much that isn't, in the tentacle-hentai rainforest. Nearly everything that isn't itself hentai-tentacles is either benign to the point of being hypoallergenic, edible, a natural aphrodisiac drug, or both.
So there's no reason not to explore.
Mira spots a strawberry the size of a fist growing under a branch as she walks by, plucks it, and moans softly as she bites into it. She passes a large flat-topped mushroom that her isekai knowledge tells her is nutritious and tasty. She casts a Construct spell, building a crude knife from platonic solids, and cuts herself a slice like the mushroom's cap is some kind of pie.
She finishes her snack and moves on.
