Digging It Escape from Giantess Dungeon! chapter 5 by SuperKirby

The door to Olibe's cell is sealed shut by at least three locks of different shapes and sizes; it would take far too much time and effort to swipe the correct keys and unlock the way to freedom. Just then, you notice a small crack in the floor...and your brain quickly hatches an idea! Perhaps you and your goblin cellmate could dig through that crack and create an escape tunnel! You relay your plan to her.

"Eh, ya sure that'll work, little fairy?" Olibe responds, releasing her grip on your small form. "All I got ta dig with is my dagger. Didn't think ta bring my trowel or anythin' else in here, because...reasons."

Now that's a convincing argument. Well, it looks like you and Olibe will have to work with the tools you've got on hand. Oh, and also your magical fairy powers! You whisper a spell, which gradually widens the floor crack until it's just big enough for Olibe to dig through with her knife. With that done, she begins to carve a getaway tunnel bit by bit, while you continue using your magic to soften the soil around you and make the goblin's job much easier in this underground darkness...
