Plato (voiced by Norman Mikeal Berketa) is a grey porcupine that lives on the branches of a tree in the Great Forest. Although not exactly a friend of the Toad Patrol, he does help them with two rambuctious flying squirrels and an adamant woodpecker.
Crabby and stubborn, Plato listens to no one and prefers to be left alone. He's incredibly lazy, as seen when he sleeps throughout the day and refuses to budge from his branch to let the Toad Patrol pass. The porcupine hates to be bothered during a nap. Thanks to his large size, Plato can be intimidating to other creatures living in his tree, which gives him authority over them. However, he is not mean by nature, and simply wants peace and quiet.
