Marble bag

The marble bag is one of Mikey's possessions. Meant to hold marbles, it's co-opted to hold gemstones instead.

Details
Mikey's marble bag is a simple cinch bag with a black Marble King logo printed onto it.

Involvement
The marble bag is first seen as the Goonies prepare to leave the Walsh residence to go after One-Eyed Willy's hidden treasure. Later, when they are on the Inferno, Mikey empties the marbles to make space for extra treasure on his person. Tucked away safely in his jean jacket, the Fratellis don't notice it when they make everyone empty out all the goods they have on them. It's forgotten about and is rediscovered by Rosalita while handling the Walsh boys' clothes. After getting the attention of everyone, she empties the bag into Irene Walsh's hand, revealing the treasure that saves the Goon Docks from destruction.
