In the Jungle-like forest, near the oil fields, while looking for the wreckage of the Cybertronian ship known as The Ark, which crash landed in the desert sand, nearly injuring the Cybertronians and everyone on the ship, you hear a noise. While you saw claw marks on a tree or a rock, a giant sized fossa suddenly appears, but recognized you.

Bone Fossa: "Hey there. Name's Bone. Bone Fossa. I'm a fossa. Nice to meet you."
