Tricky Bag of Tricks

This small sack looks normal but for constantly changing colors. The bag feels empty until you
reach inside where you will feel a small fuzzy ball.
You can remove the ball and throw it up to 20 feet.
Roll a d6 to determine what color the bag is at the
time the ball is thrown (1-2 for gray, 3-4 for bronze,
5-6 for rust) then roll a d8 to determine what beast
the ball becomes. The creature is friendly to you, acts on your turn, and you can give it simple commands as a bonus action. 2 charges/day
