She needs a couple hands, and gets two.

As Brenda shifts and strains her muscles trying to free herself, little bits of dirt and pebbles rain down on her from above bouncing off her new form... Bit by bit as she rocks back and forth slowly Brenda works herself free, the soil and rock giving way under her might as she manages to barely roll over onto her front. A small burst of victorious laughter spills from Brenda's mouth even as more and more earth and stones rain down on her shell. "Ha! Not gonna let a little cramped tunnel get the best of me, just gotta crawl a bit and I'll be home free-" Starting to move a bit the ceiling groans and finally collapses right on top of Brenda. Heaps of soil squashes Brenda to the tunnel floor covering her shell and sealing the tunnel in half.

The tiny cave in left Brenda's arms pinned beneath her and the dirt, with just her head and neck poking out of the soil on the front end. Behind her her legs and plump rump were uncovered along with her thick tail. She attempts to move... but despite her wiggles she can't move and inch as she is forced to take shallow breaths. "Damn... G-gotta get out from... This... Can't... move- Agh!?"

Brenda jolts as she feels hands on her thighs from behind her, she can pick up something being shouted but it is too muffled by all the earth to understand. She feels a second set of hands join the first on her thighs and she wiggles a little her tail twitching behind her.
