You do not sleep, cannot be put to sleep magically, and may fill rests with light activity.

When the mending spell is cast on you and you have 0 hit points you become stable. Alternatively, as part of the casting of mending the caster may expand any number of spell slots(minimum 1) causing you to regain a number of hit points equal to 1d8 + their spellcasting ability modifier. When you do this using a spell slot of 2nd level or higher, the healing increases by 1d8 for each slot level above 1st.

While motionless you appear as a normal stuffed animal. This gives you advantage on stealth checks.

When you finish a long rest, you can choose another creature that is friendly to you to be your best friend. While you are with 5 feet of your best friend, you can use the Help action as a bonus action to help that creature. This benefit lasts until you choose a new creature as your best friend.
