Bag of Tricks (Rust)

When reaching inside the empty bag you feel a small fuzzy object. As an action you can pull the object out and throw it up to 20ft. Once it hits the ground roll a D8 to determine what it becomes.
1-Rat, 2-Owl, 3-Mastiff, 4-Goat, 5-Giant Goat,
6-Giant Boar, 7-Lion, 8-Brown Bear
Creature acts on your turn and is friendly to you and your companions. You can use a bonus action to give it simple commands, but acts naturally if not commanded. Once 3 balls are pulled, bag can't be used again until next dawn.
