The Lava Machine is a large, furnace-like machine located inside the volcano of the island of Waki-Waki. Its sole appearance is in The Super Mario Bros. Super Show! episode "Too Hot to Handle", where it is operated by King Koopa and Fryguy with the intent of flooding the island with lava after capturing Princess Toadstool.
Hearing King Koopa and Fryguy's plan, Mario and Luigi, after sending Toad to distract King Koopa, while they gather tools and begin work on sabotaging the Lava Machine by clogging its pipes, which causes the machine backfire and begin to destroy itself and the volcano instead.
King Koopa is informed of this by Fryguy after capturing Toad and threatening to throw him into the machine. Hoping to fix the Lava Machine and salvage his plan, King Koopa approaches it, only to witness one of its pipes burst, causing lava to spew everywhere. Believing the situation to now be hopeless, King Koopa tries to flee with Princess Toadstool in his Fireproof Lava Boat, only to be stopped by Mario, who causes King Koopa to trip by pulling the rope of a life preserver that he had caused King Koopa to step in.
Eventually, the Lava Machine explodes, unleashing a wave of lava which Mario, Luigi, Princess Toadstool, and Toad manage to ride to the beach of Waki-Waki on the Fireproof Lava Boat, while King Koopa escapes from it using a Mask Gate; how Fryguy escapes this large flow of lava is unrevealed, but he is shown to be alive at the end of the episode, having been captured by the Fire God.
