Season 2 Episode 4 – City Under the Sea

The Sullivan Family are visiting sunken Bay City (long abandoned by rising tides) when they become trapped in their rental sub.

Falling debris from The Mechanic is to blame — he’s tearing up a fallen skyscraper with a Crab Ship.

Kayo (voiced by Angel Coulby) and Gordon (voiced by David Menkin) dispatch to the scene and try to get along while they work to rescue the Sullivans.

Meanwhile, Lady Penelope and Parker take FAB1 to the Creighton-Ward building and race to recover a valuable set of blueprints to Parkmoor Scrubs Prison before the Mechanic finds them first.

When the villain strikes at them, Gordon must go EVA to save the Sullivans, leaving Kayo in charge of TB4.

In the end, the duo save the Sullivans and the blueprints are destroyed before the Mechanic can make use of them.
