Oilspill Island was complete chaos! Trolls had taken over, captured the Gillman, and were drilling for oil. Gill had the eerie feeling that the Trolls would have fish sticks for their lunch break. Wham Shell readied his mace. If this is what his kingdom would have become, he would have a very deep hatred for trolls. "ALERT! ALERT! INTRUDERS AT ACCESS PLATFORM ALPHA!' An alarm blared. Quickly, the Water Skylanders took out the Troll Greasemonkeys, Blaster Trolls, Troll Grenadiers, Mark 31 Troll Tanks, and Tech Spell Punks. Eventually, all the Gillman were freed, but the Skylanders' work wasn't done yet. "This factory's polluting the waters and mucking things up!" Gill said. "There must be a way to destroy it!" "There might be." Wham Shell said. "If we get our hands on one of those bombs, we might be able to throw it into the main reactor shaft, causing a chain reaction, destroying this factory, and complete our pollution solution." Gill quickly grabbed a bomb, only to find it lit! Quickly, he ran towards the main shaft and threw the bomb as its fuse was getting shorter! Then, KA-BOOM! The shaft exploded, and the factory was destroyed. With his people saved, Gurglefin thanked the four heroes.
Back at the Ruins, Gurglefin had just finished building his Oil Donkey. Luckily, the Far Viewer was rusty, and needed oil. After oiling it, Hugo was able to see the next component of the Core of Light: The Twin Spouts of Ocea-Major-Minor, which would house the Eternal Water Source. However, it was held in a pirate hideout called Dark Water Cove. So, despite Gill's secret hatred of pirates, the four Water Skylanders went with Gurglefin to seize the spouts!
