Plankton's tank is a vehicle that appears in the episode "Atlantis SquarePantis" and some of its book and video game adaptation, as well as the game Nickelodeon Kart Racers 2: Grand Prix.
Description[]
It is a large, green tank with a long rectangular window to see out from, and it has many levers in and out of the vehicle that can expand easily. It can only release ice cream.
Role in series[]
In both "Atlantis SquarePantis" and SpongeBob's Atlantis SquarePantis, Plankton steals the tank from the Atlantean Armory.
"Atlantis SquarePantis"[]
It is assumed that Plankton goes straight from the armory to the front of the building, assuming that the tank has very powerful fire power. He then fires the tank at SpongeBob and his friends, but it turns out that the tank only squirts out pink ice cream. He then exits the tank and starts kicking it, but hurts himself doing so.
SpongeBob's Atlantis SquarePantis[]
Plankton has an entire adventure that takes up two levels of the game, but this time, he is aware that the tank squirts out green ice cream. In the same game, it is shown that once Plankton was done using the tank, it is hauled away.
