Secret Mountain Fort Awesome

When Gweelok builds a teleport-a-potty, Festro and the monsters search for a place where pizza grows on trees. But when Festro went to go "boom boom" and flushed the teleport-a-potty, the monsters get stuck in another universe where they have to defeat an evil villain named Helmethead in order to reclaim the toilet of the land.

The Disgustoids disguise themselves as cops so they can walk on the surface, but whilst The Fart wants to follow the duties of a cop, all Festro, Gweelok, Dingle, and Slog want to do is pump up the jams.

The Disgustoids are delighted when Secret Mountain Fort Awesome comes to life and starts wrecking havok on the surface world, but when Fort falls in love with another mountain, Festro tries to break up the relationship, but ends up having to repair his broken heart.

The monsters bet Gweelok that if he used the Internet within 24 hours, he would have to stop using it at all times so he can hang out with them forever and ever.

Gweelok invents a special sauce to help Festro get rid of his nightmares, but after Festro overdoses on the batch, it causes his bad dreams to run amok in the real world.

When Festro's nephews pay a visit to the fort, they turn out to be complete wimps, so the gang teaches them how to be "rude crude dudes with attitude", but their efforts go too far.
