Kaiba takes a sharp breath. "Kisara, maybe, but he might not like her human form. And I don't want to spread around who she is---who knows how the townsfolk would react. They only seem to tolerate Spyro because he's cuddly and looks harmless."

He rolls his eyes fondly as he moves...but that soon turns into a mumbled curse as the ground crumbles. He immediately summons a few vines and latches them to the walls, reaching for Yugi.

"Least complicated is probably a bridge."

He starts drawing debris from the walls, morphing and stretching it downward into a very knotted vine bridge. It's not the smoothest walk, but it should work...it extends most of the way, at least. He wobbles a little crossing, but they're almost there when the bridge stops.

"I'm out of material to modify. We'll have to blast across."

For his next trick...he flares out his coat, draws a glyph to manipulate the immediate gusts of wind in a certain direction, grabs Yugi...and jumps. He keeps casting, because this jump requires a lot of wind.

It's not the most graceful landing, but hopefully it's not a spiky one.
