I have to hand it to Volo’s Guide to Monsters for giving us grungs, undisputed winners of the Most Adorable Evil Creature title, formerly held by kobolds.
Clearly based on poison arrow frogs, grungs are arboreal rainforest dwellers, tribal and territorial. In the latter respect, their behavior in groups will therefore resemble that of lizardfolk, so I refer readers to my original article on them. Their amphibian nature also invites comparison to bullywugs.
Lizardfolk are brutes, but grungs are low-Strength, high-Dexterity, high-Constitution skirmishers. Their low Strength means they’re going to be encountered in large numbers; no fewer than half a dozen at a time, I’d say. If they’re going to initiate an encounter against your player characters, rather than vice versa, they’ll have to outnumber the party at least three to one.
Grungs share the Amphibious and Standing Leap features with bullywugs. This means they’ll often be found in swampy areas, around rivers and in other sorts of difficult terrain, which they can get around in easily by jumping. They’re quicker than bullywugs, though not as quick as most PCs, and since they can climb as well as jump, they’ll use their proficiency in Stealth to hide in trees and drop on their enemies from above.
