Wacky: Your blank, soulless stare reveals nothing to others abot your intentions. You have advantage on all charisma checks.

Wavy: All ranged and thrown attacks have disadvantage against you, but you also have disadvantage on all ranged and thrown attacks. This includes ranged spell attacks, but not spells that only require saves. 

Inflatable: You have a base AC of 8. Your size is large, but you weigh no more than 50 pounds.

Arm: You have a maximum Strength score of 14

Tube: You don't need to eat, drink, or breathe. You cannot walk, swim, climb, or burrow. You can only fly if granted that speed by a seperate spell of effect. Your only natural mode of movement is a teleport. You can teleport to a location you can see within 50 feet of you. You must teleport onto solid objects, and your elevation can change no more than 10 feet. As long as the angle of the surface is less than 90 degrees vertical you can attach to it, and only an inch of your base needs to be on a surface for you to attatch to it. You can only use this feature once per turn, unless you use the dash action, in which case you may use it one additional time per dash.

Man: You are a construct, but are considered a humanoid for any prerequisite that requires you to be. Though your mouth is inanimate, you are still able to speak.
