The Ring of Fire

Summary
A series of underwater sea quakes along the ocean floor cause a research team to become trapped in their sea lab that perilously sits near the edge of an underwater cliff. It’s up to Sherbet, the mighty pups and the super royals to rescue and bring the research team to the surface, but before doing so Zuma and Pablo, discovers a device which turns out to be one of several seismic destabilises which have been left at the bottom of the ocean.

With the help of Agent Tasha, they discover that the devices causing the quakes have been created by their organisation's biggest enemy, Baddy Mcbad.

(The episode opens with a hot air balloon flying out of control through stormy skies.)

Father in Balloon: Mayday, mayday. We're out of control and gaining altitude.

Boy in Balloon: Dad I'm scared.

Father: Stay low and hang on son.

Boy: Dad!

Father: I'm at 10 thousand feet and climbing. Can anyone hear me? (He stops at the sound of engines) "What is that?

Boy: International Rescue!

(It's Thunderbird 2! She pulls up next to the balloon and Mighty Rubble with a grey bulldog called Sherbet appears at the top of her canopy.)

Rubble: Looks like you could use a little help.
