Water Glider

Amphibious: The glider can breathe air and water. 

Standing Leap:  The glider's long jump is up to 40 ft. and its high jump is up to 20 ft., with or without a running start.

Glide: While using its fly (glide) speed, the glider must descend a minimum of 5 ft. per round.

Sticky Toes: Can climb on difficult terrain and ceilings without needing to make an ability check.

Multiattack: The water glider makes two attacks. 

Tongue: Ranged Weapon Attack: +7 to hit, range 15 ft., one target. Hit: 6 (1d4+4) bludgeoning damage and the target is pulled 10 ft. towards the water glider, and is restrained as though it were hit by Bite. 

Bite: Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 15 (3d6+5) piercing damage and the target is restrained. As an action, a restrained target can make a DC 15 Strength (Athletics) or Dexterity (Acrobatics) check to escape. Until the creature escapes or is swallowed, the water glider cannot use it's tongue attack or bite another target.

Swallow: The water glider makes one bite attack against a larger or smaller target it is restraining. If the attack hits, the target is swallowed. The swallowed target is blinded and restrained, it has total cover against attacks and other effects outside the water glider, and it takes 15 (6d4) acid damage at the start of each of the glider's turns. If the glider dies, a swallowed creature is no longer restrained by it and can escape from the corpse using 10 ft. of movement, exiting prone.
