Ice King, Neptr, Tree Trunks, Shelby and Lemongrab must work together to escape a dungeon they mysteriously awaken in.

Plot
The episode starts out with Ice King, Neptr, Tree Trunks, Shelby, and Lemongrab awakening in a dungeon. Lemongrab starts to say weird words, leaving the others in confusion. Tree Trunks asks Lemongrab what he just said, and he says he was reading the words on the wall. Then, all the characters start reading the wall.


 * "Awake, avast, hold tight your buns, if buns you do hold dear

For time has come to wake and run and not give way to fear

Beyond this room are a thousand rooms, outside of them still more

Behind each door, on every floor, danger, danger, ever more.

Stranger, hark! The traps galore may kill you whilst you do explore

To free yourself from this tomb, and nevermore re-enter

Find the room amidst the rooms that lies exactly center."

Next, the walls start to come in on everyone. Everyone panics as they look for a way out. A door opens, and Tree Trunks runs through it, but ends up falling. Neptr eventually ends up saving her. Lemongrab gets angry, and he scrapes his finger across the floor. A door opens up, and everyone falls.

Everyone thinks they'll never get out of the dungeon, because there isn't a door. Lemongrab asks how Ice King tastes. Ice King says he doesn't know. Lemongrab gets angry and screams, "MILD OR SPICY?!" Ice King remembers him kissing his hand, and he says "lonely." Neptr finds an oven and says he can cook. Tree Trunks says she can cook an apple pie. Minutes later the pie is done. Everyone smells it as well as a rat. The rat comes out of a door, and it eats the pie. Lemongrab hits it, and he starts eating out of its mouth. Everyone else is in disgust. They remind Lemongrab that the rat lead them to the next part of the dungeon.

The next dungeon is a room with a large body of water making hot steam with a monsterous fish tied to a plug in the bottom, Ice King tries to fly but the heat grew him tired,, he tries to freeze the water but it quickly evaporates, he gives up and tells the others they can have his corpse for food. Shelby thinks of an idea, he lets Tree Trunks float in the water with a knife tied to a rope, the monster eats Tree Trunks then Ice King and Neptr pulls the rope pulling the monster out of the water, unplugging the hole and draining all the water. Tree Trunks cut open the monster to get out and leads the group to the next door.

The next dungeon is a room with a giant tentacle monster, Lemongrab then starts runningaroun with his sound sword, the monster picks him up and squeezes him causing all his juice to squirt on the monster. The monster exploded causing another door to open. The group runs to the other room and falls down but they were saved by the Ice king. When they landed, Neptr explain that the next door is protected by an Esso teric encryption system. But Ice King confuses him to be Beemo and said he grabbed the wrong robot. Tree Trunks get angry and makes the Ice King confess. The Ice King explained that he brought them all there for thier special atrributes to get pass the dungeon and saying that he should have grabbed Beemo instead of a robot he doesn't remmember.
