Haunted Hollows takes place in a cavern submerged in water. During the first half, Dixie and Kiddy must swim underwater and avoid some aquatic enemies along their path, including Bounty Basses, Lurchins, and Kocos. The second half takes place outside the water, and it becomes a normal cavern level akin to Stalagmite Frights. The Kongs encounter many types of enemies on land, such as Krumples and Kuchukas. Despite the level's name, there are no haunted features in the level aside from one Boo Barrel just before the Level Flag, where it boosts the Kongs upward. Squitter the Spider is playable during the second Bonus Level.
From the start of the level, the heroes need to swim through a damp cave. They swim west as they travel, avoiding Bounty Basses and Kocos. Eventually, the group find a straight, underwater pathway where they need to dodge a few Lurchins to survive. Past this area, the heroes have to swim a little farther west and then head upwards to reach the next area. There, they need to begin traveling east and watch out for more underwater enemies, mainly Kocos. After a while, the group approach the shore of the water, where they have to dodge several Lurchins. After the letter O, the monkeys see a barrel above them. They must jump into it to blast to a higher level of the area. From there, they need to travel up a few stony ledges, without stepping on any Bristles, and then hit the Star Barrel nearby.
Halfway through the level, the apes have to walk west and defeat several enemies, including the mighty Krumples. Eventually, they find another barrel. Jumping into it, they are shot to a higher area, where they need to beat two Re-Koils. Soon, they are greeted by a Kuchuka and a Knocka. They need to pass them both and jump over a few Krumples to find some Sneeks and Krimps. After passing all these foes, Kiddy Kong and Dixie Kong find a barrel. They have to jump into it and blast to an even higher area. There, they, again, have to defeat some Re-Koils and a Sneek. Afterwards, they find a couple of Kuchukas. They must dodge the two foes and head more westward to find more enemies. After passing the level's final Kuchuka, the Kongs come across the Level Flag.
