Outward Reach. The attacks of the Adeopapposaurus can have a range beyond 5 feet if they are listed as such. 

Close Combat Klutz. The Adeopapposaurus has disadvantage on attack rolls made against creatures within 5 feet of it. 

Multiattack. The Adeopapposaurus can choose to make a single standalone attack or it can choose to make two attacks. If it chooses the latter, it can make one attack with the use of its tail and the other with its claws. For example, either Blurred Whipcrack or Whipped Airborne Debris can be used in quick succession with Shredding Claws. 

Blurred Whipcrack. Melee weapon attack. +5 to hit, reach 5 ft. one target. Hit: 7 (1d8+ 3) slashing damage. The Adeopapposaurus shifts its haunches and then whips its tail low over the terrain towards its opponent as quickly as it can. If the attack is successful and the opponent is of medium size or below, the opponent must make a DC13 dexterity saving throw, or they trip and fall prone. 

Whipped Airborne Debris. Ranged Attack: +7 to hit, range 10 ft., one target. This attack can only be used directly after the Adeopapposaurus used Blurred Whipcrack.

Roll a 1d6 to determine the severity of the damage the debris does.

(1-2) Small Debris - Hit: 4 (1d6+1) bludgeoning damage. (3-4) Moderate Debris -  Hit: 5 (1d8+1) bludgeoning damage. (5-6) Large Debris - Hit: 6 (1d8+2) bludgeoning damage. 

If the Adeopapposaurus is on terrain with any kind of loose debris within 5 feet of it (sand, soil, small rocks, sticks, rubble, etc); the Adeopapposaurus can choose whip its tail into the debris and send it airborne. It sends the loose debris flying in the general direction its opponent. If there is no loose debris, the attack cannot be used and will automatically fail.  

Shredding Claws. Melee weapon attack. +4 to hit, range 4 ft., one target. Hit: 6 (1d4+1) slashing damage. The Adeopapposaurus rears back on its hind legs and uses its tail for balance. It then slashes at the opponent with the short curved claws on both of its front feet. 

Acidic Spit. Ranged attack. +6 to hit, range 8 ft., one target. Hit: 5 (1d4+2) acid damage. The Adeopapposaurus bring up some of its stomach acid, mixes it with its saliva in its mouth, and spits the concoction towards its opponent's eyes.

The opponent in question must make a DC 14 dexterity saving throw. On a successful save, the acidic spit misses hitting the eyes. On a failed save, the acidic spit strikes the opponent in the eyes and they are blinded for one turn.
