While Keen explores the Dark Swamp he gets across the Dartfrog for the first time. These harmful creatures are native to Krile's swampy regions. Keen surveys a rich subterranean cave fauna densely populated by lianas and twiney, cirrus-like plants. Here and there a Larvbat might appear.
On completing this level Keen will march into the nearby, next preliminary accessible Level; Murky Marsh.
In the secret, quite swampy part of this level Keen can encounter at least 9 extra lives. To get access to this spot, Keen must locate a way on the very left side of the level while using the falling platform.
