race features:
Amphibious.
You can breathe air and water and have a swimming speed equal to twice your walking speed.
Tongue-lash
So long as the use of your tongue is not inhibited, your unarmed strikes are considered to have the Reach property. Additionally, you can make minor interactions with your tongue, such as activating buttons, casting touch spells or retrieving small items, from a distance of up to 10 feet.
Standing Leap
The bullywug's long jump is up to 20 feet and its high jump is up to 10 feet, with or without a running start.
Swamp Camouflage
You have advantage on Dexterity(Stealth) checks in swampy terrain, and you may take the Hide action when lightly obscured by murky water.
Slimy Skin
You have advantage on Strength(Athletics) and Dexterity(Acrobatics) checks to escape or resist a grapple because your skin is so damn slipper.
Life as a bullywug is nasty, brutish, and wet. These frog-headed amphibious humanoids must stay constantly moist, dwelling in rainy forests, marshes, and damp caves. Always hungry and thoroughly evil, bullywugs overwhelm opponents with superior numbers when they can, but they flee from serious threats to search for easier prey.
Bullywugs have green, gray, or mottled yellow skin that shifts through shades of gray, green, and brown, allowing them to blend in with their surroundings. They wear crude armor and wield simple weapons, and can deliver a powerful bite to foes that press too close.
Unruly Diplomacy.
Bullywugs love nothing more than lording over those who trespass on their territories. Their warriors attempt to capture intruders rather than simply slaying them.
Captives are dragged before the king or queen — a bullywug of unusually large size — and forced to beg for mercy. Bribes, treasure, and flattery can trick the bullywug ruler into letting its captives go, but not before it tries to impress its “guests” with the majesty of its treasure and its realm. Struck with a deep inferiority complex, bullywug lords fancy themselves as kings and queens, but desperately crave the fear and respect of outsiders.
