Capybara

Calming Touch. If a capybara comes to a creature on its own free will, it can allow the creature to pet it. When the creature pets the capybara, it removes one bad effect/condition on the creature.

Inspiring Lick. The capybara can use half of its movement to lick a creature. The licked creature has advantage on their next attack roll and their self esteem raises.

Pack Tactics. The capybara has advantage on attack rolls against a creature if at least one of the capybara's allies is within 5 feet of the creature and the ally isn't incapacitated.

Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., 1 target. Hit: 5 (1d6 + 2) [piercing] damage. 

Judging Gaze. As a reaction to getting hit, the capybara can stare at a creature for one turn with a criticizing look, the target's self esteem lowers and they have disadvantage on their next attack roll.
