The Widening Gyre
Colonel Rozum requests the aid of Ben and his team investigating the disappearance of Rozum’s sister and two secret agents in the Great Pacific garbage patch. Arriving at an island of trash, Ben and the team confront mutated seagulls and monsters made of trash. Encountering the agents, they learn that the world governments attempted to destroy the garbage vortex by firing an experimental, plastic-eating bacteria at it; instead of destroying the vortex, however, the garbage achieved sentience and began capturing ships. The garbage monster reveals it is sentient, and begins moving to San Francisco. Ben turns into Way Big and defeats the garbage monster by throwing it into the sun, but the vortex still remains out in the Pacific.
