Bath Beasts or Tub Toddlers

Sensible cutie. The Bath Beast or Tub toddler will only attack a creature that attacked it. It'll also refuse to attack if it believes it's unsafe. It'll believe it's unsafe when:

1. They can see one of the creatures that attacked it after it lost 80% of it's max HP.

2.  They can see a creature that dealt damage to it equalling 30% or more of it's max HP. 

3. They're near a terrain or object that it believes may deal damage. Weather it believes a terrain or object may deal damage is up to the DM's deaccession.

Tub tantrum. Every time a Tub Toddler takes damage they must role a D10. If a 10 is rolled this way, they may ignore the rules of Sensible cutie for 20 minutes. If they are already ignoring the rules of Sensible cutie, rolling a 10 from this effect will reset how long the 20 minutes not add to it. 

Cast iron cauldron. For every 5 ac the Bath Beast will decrease all damage it takes by 3. For every 10 ac the Tub Toddler will decrease all damage it takes by 1.

Shower of mist. These creatures can secrete a mist that lightly obscures vision in a 40 ft sphere if they believe that they're unsafe. The mist will disappear after 2 rounds or 15 seconds outside of combat. Bath Beasts can use this ability on their turn every 5 rounds or every minute outside of combat while Tub Toddlers can only use this ability on their  turn once every 15 rounds or every 3 minutes outside of combat.  

Sauna sense. Once per the Bath Beast's and Tub Toddler's turn, if their lid is closed and they are within mist, they can make a wisdom check. If it gets a 10 or higher it knows the exact location, species and tools of all creatures that aren't airborne within a 80 feet radius. It vibrates and makes a cute grumble sound that can be heard within 15 feet.

Closed lid. On the Bath Beast's and Tub Toddler's turn, they may close their lid. They will also immediately close their lid after taking damage or if they move. When the Bath Beast's lid is closed it gains +5 temporary ac while the Tub Toddler only gains +3 temporary ac. In this stance neither can preform attack actions. They can't enter this stance while already in it. If their lid is closed for 5 days they will die.

Tipped Trash. Upon taking 50% or more of their max HP as damage in a single hit or if they move. They'll tip over on to their round side. They can't return to being upright unless helped by another creature. They know when they're tipped and won't open their lid until they are up right. If the lid is opened all water will gush out.

Hot Spring. Body Attack: +7 to hit, reach 5 ft., one target. Hit: 2d4 + 2 bludgeoning damage. The Bath beast moves forward 9ft and hits a 6ft x 6ft radius in the direction of it's target. They will not use this attack unless they have lost 70% of their max HP.

Soaking Slap. Hand Attack: +5 to hit, reach 5 ft., one target. Hit:  1d4 + 2 bludgeoning damage. 

Bowl roll. Pick 1 target within view. The Bath Beast or the Tub Toddler will roll 100 feet in a direct line towards them, only stopping if it hits the target or a solid object. If they would hit the target, the target must make a dexterity saving throw of 15 or higher. 

Upon failure the target takes 3d6 +8 bludgeoning damage if hit by a bath beast. If they fail the role to a Tub Toddler then they take 3d6 bludgeoning damage.

Upon success they takes half the respected damage that they would have taken on a failed roll.

If the bath beast hits a solid object 1st than it stops where it is and takes 1d8 bludgeoning damage. Tub Toddlers will take 1d10 bludgeoning damage and bounce 5 feet backwords in the opposite direction, upon hitting a solid object.

Open lid. On the Bath Beast's and Tub Toddler's turn, if they think they're safe these creatures may use a bonus action to open their lid. They can't enter this stance if already in it. Any bonus ac gained by the closed lid stance will be removed but they regain the ability to preform attack actions.

Wash worry. These creatures may close their lid as a reaction.

Rinsed retaliation. As long as the Bath beast hasn't used Wash worry as a reaction in the same turn, the bath beast may use a reaction to preform any of their attacks. It won't be able to use Wash worry until their next turn.
