Critter (5e Creature)
From D&D Wiki
Small beast, unaligned
Saving Throws Constitution and Charisma
Seemingly Innocent. To those who are unwary to a critter, they are seemingly adorable and cute, showing no threat whatsoever. This gives them on deception rolls against unwary prey.
Critter Bite Melee Weapon Attack: +2 to hit, reach 5 ft., one target. Hit: 6 (1d4 + 4) piercing damage.
Critter Claws Melee Weapon Attack: +0 to hit, reach 5 ft., one target. Hit: 4 (1d4 + 2) piercing damage.
Roll Attack Melee Weapon Attack: +0 to hit, reach 10ft., one target. Hit: 4 (1d4 + 2) bludgeoning damage. The Critter essentially is able to roll into a ball and fly through the air, thus attacking the target and returning to its original location without causing a opportunity attack. Consider this similar to a Rogue's Cunning Action, except the bonus action is only Disengage.
