Kilwala is an enemy in Chrono Trigger. First appearing in the Mystic Mountains during Prehistory, NPC Kilwalas also appear in the Denadoro Mountains in the Middle Ages and Porre's Snail Stop in the Present. Spekkio's second form is a Kilwala.
The one atop Denadoro Mountains will give a Magic Tab if talked to four times. It'll first say: "Mountains are nice." Then: "This's the life." Then back to what it first said. Finally, he'll say: "Man, you're nosy. Here, take this." and give you the Magic Tab. If you talk to it after, all it'll say is "Mountains are nice."
Also when checking a bush in Guardia Forest in the middle ages a Kilwala will jump out and flee leaving a Shelter behind.
