"Sand Castles in the Sand" is a SpongeBob SquarePants episode from season six. In this episode, SpongeBob and Patrick use their sand creations to battle each other.



SpongeBob and Patrick plan to go to the beach for the entire day, which they decide to take the bus. As they play on the beach, they inadvertently destroy the life guard tower. The life guard, angry, suggests they play in the sand somewhere else.
121a - Sand Castles in the Sand (065)

Later on, the two decide to build sand castles. After Patrick destroys SpongeBob's sand castle, SpongeBob draws a dividing line between them to end their dispute, but in vain. Patrick builds a castle on top of the line. SpongeBob damages the sand castle, only for Patrick to retaliate by destroying his again.


SpongeBob reconstructs his castle, but to a massive scale that rivals the size of an actual castle. Patrick responds by building one of his own. SpongeBob, hoping to avoid an all-out war, writes a peace treaty. Patrick signs it, but then later changes his mind, saying it "isn't worth the sand it's printed on" (The treaty disintegrates immediately after) after he fires an arrow at SpongeBob's fortress. SpongeBob, in turn declares war on Patrick and begins to improve the durability of his fortress. While he is doing so, Patrick builds an army of horse-mounted knights.

SpongeBob in self-defense builds a catapult and uses it against the knights as they storm towards him. He then summons his own troops to attack Patrick. Patrick retreats into his castle and returns with a cannon, in which he attacks SpongeBob's hit squad. The hit squad retreats, and SpongeBob manages to get them safely back inside his own fortress. It is in vain, however, the cannonball finds its way over the fortress wall and smashes them.

SpongeBob in retaliation builds a tank to destroy Patrick's fortress, while Patrick comes with a giant robot. The tank and the robot clash, and the robot gains the upper-hand by picking up SpongeBob's tank. As it prepares to crush the tank, SpongeBob fires the tank's cannon monsters and destroys Patrick's robot. He for the next moment thinks he is victorious, but Patrick returns on the robot's head, which has separated from the body and is now an airship.

SpongeBob pulls out a remote control and pushes a button on it, calling in a fighter jet which he hops into the cockpit and takes control of. As Patrick tries to run, SpongeBob has two missiles from the fire jet chase him. Civilians on the beach begin to flee in terror. Patrick deploys a surface to air missile launcher from underneath the ground. He has it fire its eight loaded missiles at SpongeBob, destroying the two missiles that were chasing Patrick in the process. SpongeBob takes evasive maneuvers and manages to get them to fly into Patrick's fortress, completely destroying it. Patrick in a final act of retaliation uses his airship to blow up SpongeBob's fortress. SpongeBob is extremely enraged by this, and putting all sensible options aside, he flies his fighter jet into Patrick's robot head airship, destroying both aircrafts and hurting Patrick and himself.

SpongeBob and Patrick are lying wounded on the beach, apologizing to each other for trying to destroy the other when the life guard shows up and demands they clean the mess of debris and rubble left by the fight. They do as he says, tidying the beach up to its original condition but soon begin to compete with each other over who could do so faster as a sunset approaches.

  • This episode mainly takes place in Goo Lagoon. Out of 11 minutes, the first minute and 30 seconds of the episode takes place at Patrick's house and inside a bus.

  • A sand dollar also appears in the video game Revenge of the Flying Dutchman.
  • SpongeBob (Sir SpongeBob) and Patrick (Sir Patrick) use cannons instead of rifles, machine guns, SMG's, sniper rifles, rocket launchers, armored vehicles (except Sir SpongeBob, who is using the British Crusader tank), AA and AT guns and aircraft (except Sir SpongeBob, who is using the jet plane).

Cultural references

  • The episode gets its title from a season 3 episode of How I Met Your Mother of the same name. However, in that series, the episode title is spelled as "Sandcastles in the Sand" instead of "Sand Castles in the Sand."
  • This episode is a reference to the 1986 Japanese anime film Castle in the Sky.
  • The sand robot Patrick builds to fight SpongeBob looks a lot like Commander Yammark from Mega Man 6. Except, it does not have wings and the sand replaces the head, hands, propellers, and chest. The biggest resemblance is the waist and mouth plate.
  • SpongeBob quotes the famous saying "All is fair in love and war," which has been parodied a lot in popular culture.
  • The war-plane that SpongeBob flies resembles the real world F-16 fighter jet. The only contradictory occurrence is that F-16s cannot hover like his briefly did, but the newer F-35B Lightning IIs as well as older AV-8B Harriers have the technology making them able to do so.
  • This episode is a parody of Crusades and World War II.
  • The high-tech war-planning room inside the sand castle is a direct reference to the 1964 film Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb.
  • The sand robot Patrick makes resembles Optimus Prime from Transformers.
  • When SpongeBob rams his entire war-plane at Patrick's head rocket, this is a military strategy known as kamikaze, where someone will deal severe damage to their enemy at the cost of their own life. This was heavily employed by the Japanese against the United States of America during World War II.


  • When SpongeBob and Patrick are kicked off the bus beside road and SpongeBob says "No one is ever going to find us out here!," the road is gone.
  • When Patrick smashes SpongeBob's second castle, there is a wall around it. But when SpongeBob goes back to square one again, the wall is gone.
  • When SpongeBob sends his troops to attack Patrick's castle, a sand bull can be seen running out of SpongeBob's castle with the rest of his troops, but it disappears when they arrive to storm Patrick. However when SpongeBob's troops retreat from Patrick's cannonball, the bull is again seen running back into his castle.
  • While SpongeBob draws the line and then builds his wall, the line is gone when he tells Patrick's base is on the line, when the line suddenly vanishes.
  • When SpongeBob goes kamikaze on Patrick by ramming him with his jet and they fall down, SpongeBob is shown with bandages even though he did not have any.
  • After the camera pans over the destroyed beach, SpongeBob and Patrick's scratches and bandages disappear.
