McDungeonland

In the proud tradition of the EX series of modules, consider this isolated valley (or maybe a demi-plane) inhabited by strange creatures--some of them with foodstuffs for heads...

Stranglely, despite being part foodstuff themselves, the inhabitants cheerfully consume the talking food that exists ready-made in their environment: There are patches of cheerful "hamburgers," trees that grow apple pies, a lake teeming with breaded and fried fish, and even a small volcano which oozes a frozen chocolate beverage.

The strange land is not without its dangers.  There are small, bespectacled goblins ("gobblins"), shaggy and colorful, who will steal food from the unaware.  A humanoid of piratical dress and demeanor wll menace those who take the fried fish from the lake.  A masked humanoid thief in cloak and stripped outfit likewise steals food, but he favors beef.  Finally, there is a purple blob-like creature that can manifest two or four arms, who is sometimes benign, but other times may attack to steal the "shakes" which emerge from the volcano.  The creature may be some sort of "shake" elemental, himself.

Though not in a overt position of leadership, the secret ruler of the land is a clown in motley with a friendly demeanor--but perhaps less friendly goals.
