Flab Boys

"One false move and we'll sit on you!"

- Flab Boys

The Flab Boys are two large, overweight rappers from the city of Rap Land. The Flab Boys take their name from the real-world rappers, The Fat Boys.

In The Super Mario Bros. Super Show! episode "Bad rap", Rappin' Koopa takes over Rap Land by invading the castle, tying up King James, and playing a hypnotic theme through the speakers all over the city. The Flab Boys are unaffected, due to the fact that they are wearing earphones.

The Flab Boys soon meet up with Mario, Luigi, Princess Toadstool and Toad when they arrive in Rap Land, and give them the lowdown on what's happened. The Flab Boys then accompany them to the castle, where Princess Toadstool tries to sneak Toad in. When Princess Toadstool's cover is blown, the Flab Boys try to stop several Koopa Troopas by hurling records at them, but they fail. Mario attacks the Koopa Troopas with his plunger, but Princess Toadstool simply winds up in the arms of Rappin' Koopa.

Fortunately, Toad manages to rescue both Princess Toadstool and King James, and they meet up with the Flab Boys and the Mario Bros. outside the castle. King James then decides that unplugging the Royal Plug is the only way to stop Rappin' Koopa's music. The Flab Boys and Luigi give Mario a boost, allowing him to reach and unplug the cord, shutting off Rap Land's power.

The Flab Boys later assist Mario and the others in a rapping duel and manage to defeat all of Rappin' Koopa's Koopa Troopas by rolling down a hill and knocking into them. After Toad manages to trip Rappin' Koopa, the Flab Boys threaten to sit on him. Rappin' Koopa escapes through a Warp Zone.

After returning the castle, the Flab Boys offer to play the Mario Rap, which everyone dances to, as a celebration of Rappin' Koopa's defeat.
