- "A Clayman that has grown lonely. All sorts of garbage and junk have been absorbed into its body."
- — Battle Memory
The Forlorn Junk Heap is a boss encountered in Mother 3. It is a long-discarded Clayman found in the garbage pit near the Highway, which is east of the old coffee shop, and north of the Thunder Tower.
During Chapter 5, when the party nears another moss-covered Clayman used to store Duster's Egg of Light, the garbage-covered giant springs to life and attacks. Once defeated, Duster finally retrieves the Egg of Light and restores his memory.
Like many bosses in Mother 3, the Forlorn Junk Heap has an unused back sprite.
The Forlorn Junk Heap starts the battle enveloped in a shield, which it can replenish at will. It attacks by throwing garbage at a party member, hitting either once or several times; a single-hit attack does much more damage than a continuous stream of garbage. It can also replenish HP or boost its defense using nearby scrap and junk, and produce an incredibly foul, nausea-inducing odor. It is weak against PK Fire.
Its battle sound is Battle Sound 30, which falls under Code Numbers 526 for regular attack, 527 for Smaaaash! and 528 for Miss.
