As its name suggests, Big Ravine is a large ravine. There are a couple of acacia trees near the edge of it on either side as well as several large rocks on one side only, and it has barren rock at the bottom. The walls of the ravine are composed of stone that appears slightly reddish at some angles. There are many crevices in it, and it chips away rather easily. Falling down the ravine would be a very long drop.
After hearing a cry for help, Ono seeks out a serval who has attempted to leap across Big Ravine with poor results. Fuli dashes over to Big Ravine ahead of the Guard to save him as he tries helplessly to claw himself up to the other side. She leaps over it herself, landing beneath the serval, and pushes him safely (despite almost getting kicked by the petrified serval's back paws) onto the edge of the ravine. Afterwards, the serval thanks her for her assistance, and Fuli manages to pull herself up to safety on the other side. The Lion Guard soon rejoin her by taking the long way around, all impressed by her work (save for Kion, who shows concern).
