In Mother 3Edit
Porky Minch's body has become frail and prone to violent coughing fits due to his abuse of time travel, and he uses it for both transportation and battle, where it uses inexplicable attacks. It resembles a mechanical spider (not unlike the mecha with a more organic appearance he used in the final battle of EarthBound). It is first seen descending from the ceiling in Master Porky's room, hanging from two chains. The Bed Mecha also appears to have a face that has its eyes close and jaw drop when it runs out of energy in battle. Oddly, it is shown to have eight legs in-battle, but only six in the overworld.
There are unused sprites of Porky Minch where he appears in a glass capsule before it shatters and he appears to die. Whether he was intended to use the Bed Mecha in this stage of the game's development is unknown.
In Super Smash Bros. BrawlEdit
Porky uses his Bed Mecha again during The Subspace Emissary mode of Super Smash Bros. Brawl, appearing similar to how he did in Mother 3. It is shown here with eight legs, and uses a wide repertoire of weaponry, including explosive Mecha-Porkies, lasers fired from the head of the bed, and a rapid flurry of jabs from the mecha's legs.
