Gokudera seems to either ignore the bubble or not see it at all as he approaches the brush and sets his hand on a leaf. The surrounding leaves seem to ripple like the surface of water and change to scales, and then the creature appears, the bush vanishing. It's roughly the size of a horse and lifts it neck to look down at him, cocking it to the side, opening its mouth and burping another bubble.

"What the hell..." Gokudera looks at his hand, then touches the creature again, running his hand over its neck as it blinks one eye, then the other before making an odd gurgling noise.

Lily may be able to hear it say something about being hungry, but Gokudera doesn't seem to be able to understand. It's talking to the girl, and likes her better. She hasn't yelled at it.
