This bag functions similarly to a bag of holding. It has an interior space of roughly 27 cubic feet, it weights 6 lbs regardless of its contents. Retrieving an item from the bag takes 1 action.
When retrieving an item roll a d20. On a 1 or a 20, instead of withdrawing the intended item, you pull out a goose instead. on a 1, the goose is hostile to you. On a 20 the goose is chaotic neutral. If no one is actively observing the goose, it vanishes. Presumably back into the bag.

If the bag is overloaded, pierced, or torn, it ruptures and is destroyed, and its contents are scattered in the Astral Plane. If the bag is turned inside out, its contents spill forth, unharmed, but the bag must be put right before it can be used again. Breathing creatures inside the bag can survive up to a number of minutes equal to 10 divided by the number of creatures (minimum 1 minute), after which time they begin to suffocate.
Placing a bag of holding inside an extradimensional space created by a handy haversack, portable hole, or similar item instantly destroys both items and opens a gate to the Astral Plane. The gate originates where the one item was placed inside the other. Any creature within 10 feet of the gate is sucked through it to a random location on the Astral Plane. The gate then closes. The gate is one-way only and can’t be reopened.
Notes: Utility, Container
