You have a tail that you can use as an extra limb to grab and hold onto small things around you. The tail can manipulate an object, open or close a door or container, pick up or set down a Tiny object, or wield a weapon that has the light property. This tail can wield weapons with the light and finesse property as well be used to unlock a lock. If your tail isn’t grappled you can use it to attack with a weapon it is holding without having to roll disadvantage. You can also use this tail to hang upside down given you have the area to do so using your tail allowing you to use both of your hands.
You can move through the space of any creature that is a size larger than you, but you can’t stop in the same space.
