Rocks
From Muppet Wiki
The Rocks of the Labyrinth seemingly come alive when Ludo calls for them. From the smallest stones, to the largest boulders, Ludo is able to control these rocks. Most often, he uses this power to protect and help his friends, as when he summoned up a path of stone at the Bog of Eternal Stench.
The rocks were largely responsible for the defeat of the Goblin Army.
