Beans

Keen Hearing. Beans has advantage on Wisdom (Perception) checks that rely on hearing.

Hide! When overwhelmed Beans likes to find somewhere quiet and small to hide, if no place is within sight she will curl up between Wren's ankles or on their lap if sitting.

Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one creature. Hit: 1 piercing damage.

Sit/Lie-Down. Wren can command Beans to stop what she's doing and sit in place or lie down.

Stop/Move. Wren can command Beans to stop what she's doing and pay attention to them, or to move to a specified location that Beans can see within 30ft.

Wait. Wren can command Beans to wait where she is for up to 20 minutes or 4 rounds of combat after the command is given. Beans will move if harmed in any way and will not stay anywhere he does not feel safe.

Make Noise. Wren can command Beans make an audible noise on command. In response to a command word, Beans will make a loud noise if they are capable. This can be used to locate Beans if she is not in sight.

Carry/Deliver. Wren can command Beans to carry something that is of realistic size and weight for Beans to be able to carry. The DM can determine how long Beans can carry the object before becoming too tired. Wren can also use this command to have Beans deliver the object to someone or somewhere that Beans can see when the command is issued.

Push/Pull/Open. Wren can command Beans to push/pull/open something within eyesight of Wren, this must be something Beans can realistically be able to move. Beans can also give a bonus to Strength checks that require Wren to push or pull something (+1 bonus total). 

Find/Retrieve. Wren can command Beans to find something in a designated area. Beans must have reference material to achieve this, for example something she can smell or an object she can recognise. Without this she will find something he considers interesting or nothing at all.

Once Beans has had time to study the reference matieral she can make a Wisdom (Survival) or Wisdom (Perception) check with advantage, using Wren's proficiency bonus (+5) to add to the roll
