Marshmallow

Marshmallow is a type of confectionery that is typically made from sugar, water and gelatin whipped to a squishy consistency. It is used as a filling in baking, or commonly molded into shapes and coated with corn starch.

Marshmallows come to life when close to the edge of Marshopolis whilst at the same time a specific signal is being emitted, nobody knows what the signal is and how it is sent, recieved, and returned, only because it is the Marshopolians who made the tech.

Sometimes instead of specifically saying Marshopolians some tend to say marshmallow to show they are speaking of a wider variety.
