"Who R Zoo?" is a SpongeBob SquarePants episode from season 12. In this episode, SpongeBob and Patrick create their own zoo made entirely of bubbles.



Who R Zoo 032

SpongeBob gets kicked out of the Zoo.

The episode begins with SpongeBob playing with the zoo animals at the Bikini Bottom Zoo until the zookeeper stops him from doing so, telling him it's illegal to sneak into the animal enclosures because the animals are not pets and could get him injured. SpongeBob is against this, because he is friends with the animals, so the zookeeper puts an ankle alarm on him to prevent him from going into the animal enclosures, which will go off should he do it again. SpongeBob tries to evade this by keeping the foot with the ankle alarm outside the enclosures, but this fails and he gets kicked out of the zoo, with Patrick sneaking into a sea monkey enclosure so he gets kicked out with him.

SpongeBob is crying on Patrick's rock, until he gets the idea of building a bubble zoo after creating a snot bubble. They create many bubble animals as well as the zoo itself using Extra Strength Bubble Soap. The zoo is visited by many people and it is a success.

Who R Zoo 086

The Bubble Zoo.

Meanwhile, Squidward wakes up from his nap and goes outside, only to get trapped inside one of the bubble animals. After he is released, one of the bubble animals eats his clothes, causing Squidward to panic and pop the entire bubble zoo. The bubble animals get angry at SpongeBob and at the same time, invade the Krusty Krab and the Chum Bucket.

While SpongeBob and Patrick are cornered by the bubble animals, the former calls the animals from the real zoo to defeat the bubble animals. The animals come and the bubble animals get scared by the sea monster, causing them to hide in the Extra Strength Bubble Soap canister. The episode ends with the zoo manager letting SpongeBob back in the zoo for bringing back his animals as well as bringing new bubble animals.

  • This episode was originally going to be titled "Zoo Are You."[15]
  • This is the first episode to have a 2020 copyright date.
  • Throughout its run in 2020 and 2021, this episode has been paired up with different episodes, mainly because of how Nickelodeon withheld its sister episode until April 29, 2022. As of May 14, 2022, this episode is now paired up with "Kwarantined Krab."[22]
  • This was the last episode with any involvement from Adam Paloian. However, he did not direct this episode, instead providing pre-visual development and character design.[11]
    • Marc Ceccarelli and Vincent Waller directed this episode instead.[6]
      • The reason they were only credited as co-executive producers is likely due to the fact that credits do not list a crew member's name twice beginning in season 12. This can be seen with all of the storyboard-driven episodes post-"The String."
  • Squidward wears underwear in this episode, when he regularly does not even wear pants. However, he wore them underneath his farmer's uniform which doubled as regular pants.
