Jumanji: The Animated Series

Judy, Peter, and Alan get caught sneaking around Ibsen's lab and narrowly escape by way of Ibsen's submarine. In the meantime, Peter has turned into a salamander after being slimed earlier. The sub is hijacked by Squint and his crew in order to search for the undersea treasures of the lost land of Milkadanda. They dive too deep and the sub breaks apart. Alan and Judy are okay, but they'll need the help of Salamander Peter to survive.
