5E D&D Fearsome Critter: Billdad (Saltipiscator Falcorostratus)
 
 This is the latest entry in a series of creatures I converted for Fifth Edition Dungeons & Dragons from the North American myths and legends known as Fearsome Critters. You can download all 50+ monsters here
This curious creature is about the size of a beaver, but has long, kangaroo-like hind legs, short front legs, webbed feet, and a heavy, hawk-like bill. 

Billdads are best known for their peculiar form of hunting in which they use their broad tail to slap fish out of the air, stunning them. They are amazing jumpers, capable of crossing massive distances with a single leap. Billdads are also a delicacy that few creatures manage to consume due to the peculiar side-effects of eating its flesh.

Confusing Flesh. Any creature that bites the billdad must make   a DC 10 Constitution saving throw. On a failed saving throw, the creature   can't take reactions until the start of its next turn and rolls a d8 to   determine what it does during that turn. On a 1 to 4, the creature does   nothing. On a 5 or 6, the creature takes no action but leaps 150 feet in a   random direction. On a 7 or 8, the creature makes one melee attack against a   random creature, or it does nothing if no creature is within reach. Even   eating a dead billdad causes this effect. The effect ends on   a successful Constitution save.

Hold Breath. The billdad can hold its breath for 15   minutes.

Standing Leap. The billdad's long jump is up to 180 feet and   its high jump is up to 90 feet, with or without a running start. 

ACTIONS

Tail Slap. Melee Weapon Attack: +3 to hit, reach 5 ft.,   one target. Hit: 3 (1d4 + 1) bludgeoning damage and the creature must succeed   on a DC 10 Constitution saving throw or be stunned until the start of the   billdad's next turn.
