Floofs are just darn cute to most other species, and their natural defenses add to their overall toughness.  Add 2 to your Charisma score and 1 to your Constitution score.

All Floofs are able to communicate with one another in Floof, and adventuring Floofs can understand basic Common.  A Floof character with an Intelligence score of 10 or higher can also write in Common, although their vocal cords do not allow them to speak it.  Floofs with an Intelligence score of 12 or higher that learn Sylvan speak it with a distinctive accent.  Highly intelligent Floofs can learn to understand and write other languages as well, though they can only ever speak in Floof or Sylvan.

Floofs automatically tuft out when surprised by a perceived threat, changing their buoyancy and aerodynamic properties.  While tufted, they float gently to the ground at 5 feet per round rather than fall.  They bob and float on water and cannot be submerged while air is present, thanks to electrostatic properties that prevent their fur from clumping when wet.  Any attack against a tufted Floof based on bludgeoning or force, even from a powerful spell or magic weapon, is incapable of damaging them; however, the attack will send them flying at a high rate of speed, during which time they bounce uncontrollably off of anything and everything they come into contact with.  Their tufted state makes walking and running difficult, halving their movement speed.

The electrostatic forces that protect their buoyancy also deliver a high voltage static shock to any unprotected creature who touches a tufted Floof, inflicting 1d4 nonlethal lightning damage with each touch.

Floofs tuft defensively as an automatic bonus reaction under these circumstances:

• The Floof begins falling
• The Floof comes into contact with water
• The Floof is surprised in combat by an enemy

When a Floof sees an enemy attack coming, they may attempt a DC 16 Wisdom saving throw to cancel their defensive tufting bonus reaction.  Success will allow them to take a different reaction while in their normal form, according to the regular rules for combat reactions.  If they end the combat encounter without having tufted, they will randomly tuft for no apparent reason with 1d10 minutes of ending the current combat encounter or during the first round of the next combat encounter, whichever comes first.

A tufted Floof gains the following effects:

• Falling speed becomes 5 feet per round (50 feet per minute)
• Walking speed becomes 5 feet per round (50 feet per minute)
• Cannot be submerged in water while air is present
• Immune to bludgeoning and force damage from any and all sources
• Any bludgeoning or force based attack that hits the Floof pushes them in the direction of the hit at double the attacker's regular movement speed
• When pushed by an attack, the Floof bounces off any solid surface with no loss of push movement speed
• Any creature that touches the Floof with an unprotected hand or paw takes 1d4 nonlethal lightning damage

Floofs among their own, while not tufted, communicate at close range with the rustling of their fur as well as with their vocal cords.  They can communicate even complex messages to one another using only their fur, preventing any sensible form of eavesdropping from working.  They must be within 5 feet of one another in a quiet setting to use this form of communication.

As a mammal with four legs and no opposable thumbs, Floofs cannot wield any weapons effectively.  Their tiny front claws can deal 1d4 slashing damage each, and they can attack with both at once.  Floofs usually only attack defensively.

While not tufted, Floofs have very fine and precise control over their fur, allowing them to use complex tools when focused on a task.  This physical ability is not suited for high-stress situations like combat, but they can play music and pick locks, for instance.
