Ep 12. Operation Abyssness / Operation Star of the East / Operation Toxic Gas

Mister Kyoto's agents are attempting to drop iron filings at the bottom of the sea to help the aquatic environment regulate its carbon levels. Our Plankton receive the order to descend to the bottom of the abyss and sabotage the project. While Star wants (as usual) to blow everything up, Anna suggests a scientific method. The disagreement escalates into a full blown argument and they each decide to do it their own way. The gauntlet has been thrown down: who will accomplish the mission first? / The commando comes across a Japanese starfish who has been brought to Oostduinkerke against her will, in amidst a cargo of scooters. Star and Pulpo both take a liking to the poor accidental stowaway. But Anna soon discovers that the newcomer is none other than a "green spy" working for Mr. Kyoto! Will Star recognize the truth before Jensuta completely sabotages their mission...? / Green algae, produced by nitrate pollution, have invaded Oostduinkerke beach! This is good news for the commander, but he wants to take it further: he decides to send the commando in to release the highly-pollutant toxic gas generated by the fermentation of the said algae. A hazardous mission indeed!
