The Crawling Woods plunges Whiskerbottom and Ms. Fluffernugget into the most terrifying adventure of their lives. Deep within the Fur Mountains lies a hidden realm known as the Crawling Woods, a nightmarish land where the natural order is turned on its head. Here, humans shrink to the size of insects, while the realm's inhabitants—mosquitoes, bullet ants, yellow jackets, bees, and wild boars—grow to monstrous proportions, transforming the simplest encounters into life-threatening battles.

Navigating the dense, shadowy terrain, the adventurers face horrors at every turn. Giant mosquitoes swarm with deadly precision, bullet ants tower like armored giants, and yellow jackets dart like living missiles. Wild boars, now colossal predators, loom above them, their tusks slicing through the undergrowth. But the true terror of the Crawling Woods emerges when the duo is ensnared in the web of a Brazilian wonder spider—a beast of nightmarish proportions. This horrifying creature slithers through the forest with multiple snapping mouths along its sides, each armed with a lightning-fast, sticky tongue capable of capturing and killing its prey in an instant.
