Bag of Mayonnaise (Cursed magic item)

At first glance, this item appears to be indistinguishable from an ordinary Bag of Holding, but upon closer inspection it is revealed that this bag is entirely filled with nothing but Mayonnaise.

It functions exactly like a bag of holding would, but is just filled with Mayonnaise.

Note: There is a large chance that upon opening the bag at dawn, it will be once again filled with Mayonnaise. Roll a d20 at dawn, on roll 19 or less the bag fills with mayonnaise. It doesn't delete any items inside but buries them in mayonnaise.

Casting Identify on this magic item only reveals it to be a bag of holding.

Notes: Utility, Container
