Ambulatory tree beings that stride through the night town carrying monkeys in their branches.
As Carl and Princess Donut step out into the pitch-black town, a pair of tree creatures strides by without acknowledging their presence, a pair of monkeys riding in their upper branches. They are simply part of the town's night traffic — non-hostile background residents of the jungle settlement.
Mordecai had told the pair to gather mushrooms from the base of the trees in town, making the tree creatures' passage an ordinary sight rather than a threat.
Walking trees with branch-crowned upper limbs, tall enough for monkeys to ride in their canopies.
Ambient inhabitants of the jungle town, indifferent to the crawlers.
