Thunderfoot Rat (5e Creature)
From D&D Wiki
Tiny beast, neutral
Kick. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 9 (1d12 + 3) bludgeoning damage.
Parry Kick. After it is hit but before it takes damage, the thunderfoot rat can use its reaction to force the attacker to make a new attack roll to replace the last. If the new attack roll misses, the thunderfoot rat can make a kick attack against the attacker if it is in range, then perform its standing leap. The movement of this standing leap does not provoke opportunity attacks from the attacker.
The thunderfoot rat appears as an unassuming rodent with anatomy similar to a common gerbil, with sand-colored fur and abnormally thick-muscled legs. The largest of of adults can reach about a foot in length. Unlike most rodents, it maneuvers primarily by hopping with both legs in a manner similar to a kangaroo. This locomotion belies the true power of this humble rodent. Those legs are infamously powerful, and according to legend a single well-placed kick can shatter the skull of a serpent.
Thunderfoot rats normally dwell in deserts or other particularly arid and dry regions, and primarily eat fruits and small insects. Their kicks are usually only reserved for self-defense against the many hungry predators of the desert. More than a handful of humanoids have been taken for predators however, and the luckier of them got away with only a limp.
