Plot
The episode begins with Red stating that "Splashageddon" is the "awesomest day in summer", which seems like a water event. Red and Stella instruct Chuck and Bomb to pack up their stuff. Chuck poses with is towel and Bomb shouts that he's going to "build the biggest sand hole ever". Stella says that she's going to surf on Terrence's belly-flop waves and Chuck shouts "Waterslide! Waterslide! Waterslide!". Red slaps Chuck's bottom with a towel and Lynnette shoves open the the for a Cabin inspection. Lynette is disgusted by the cabin, noticing the literal toilet in the bottom bunk of a bunkbed, and 2 pizza slices on a window. Bomb defends pineapple on pizza and Lynette slaps the pizza from bomb's hand before he could potentially give himself food poisoning from it. Lynette notices a pile of dirt and socks, and forbids Red, Bomb, and Chuck from "Splashageddon" activities until they clean the cabin. Stella tries to make Lynnette clear her friends' cabin after the events of "Splashageddon", and Lynette makes her clean with them. Chuck causally drinks soap water and Lynette exits the cabin.

Bomb cries that it isn't fair and shovels dirt into a sand bucket. Red yells and Stella says that they could simply just walk out of the cabin. Stella reveals that Lynette has been behind the door, and she suggest that they should actually clean the cabin. Red objects because he thinks that it would prove that Lynette is right that they're "a bunch lazy, no-good, bums", and Bomb rhetorical asks if the description is accurate as he shovels more dirt into the bucket. Red comes with the plan to dig a tunnel to Splashageddon and, Chuck and Bomb cheer him. Bomb uses Chuck as a jackhammer and drills a hole in the floor, causing the floaties to fall off of him. Stella states that literally digging a tunnel to the lake, instead of simply just cleaning the actual cabin will take more effort. Stella reluctantly jumps into the freshly dug tunnel after Red.

Chuck and Bomb sing as they dig with literal sand castle shovels. Red tries to make Bomb explode to increase productivity. Chuck shuns Red for trying to scare Bomb into exploding, and immediately does the exact same thing he shunned Red for literally less than a second ago. Stella gives up and Red says that they should metaphorically use their heads. Chuck takes "use your head" literally and, headbutts the dirt. Stella, Red, and Chuck bounces off of Bomb's stomach to dig the tunnel, while defying the law of the conservation of matter. Chuck tastes the leaking water, and Stella abmits that Red is right. Chuck his way to the boy's bathroom and, Bomb tells that red "always comes through". They flushes their way back to the tunnel after someone starts using a urinal. Bomb and Chuck cheer on Red, and martializes a Red merchandise stand out of thin air, consisting of a "I ❤ Red" foam finger, an autographed shirt, and Red sun tan lotion. Chuck and Bomb spray lotion on each other's face's and Stella says that Red doesn't know what he's doing. They tell her to blindly trust Red, and Stella stomps the ground. Stella falls through a hole in the floor and the other jump down to save her. Bomb and Chuck slingshot Red to Stella using a towel. A stalactite falls into the lava, causing Stella to surf on a rock. Red tries to convince Stella into thinking he's "got this". Red, Chuck, Bomb and Stella pushes a boulder into a dark cave under them. They meet Rouge, who has been in the cave for 40 years while trying to go to Splashageddon. He introduces the Skeletons of his friends, Ella,Flomb, and Buck .Bomb panics, causing the lake to flood the cave and tunnels.

Red apologies for not bringing his friends to Splashageddon, and Chuck and Bomb compliment him for the adventure. Lynette notice's the clean cabin and lets them leave. The episode ends with Rouge swimming in the Lake with his deceased friends.
