The Butt-Ugly Martians return in three explosive episodes in which they continue to fool the great Emperor Bog and his henchman, Dr Damage, and remain on Earth. Their mission is to destroy the planet but their real intention is to save our World...

KooFoo
While watching a news report on television, the Butt-Ugly Martians see what is believed to be a recently discovered pyramid in the Sahara - only they recognise it as a KooFoo ship. The KooFoo have long been considered extinct and were once the most feared aliens in the entire universe, bloodthirsty renegades who were responsible for the extinction of many races of aliens. What if one or more are still alive and inside the ship?

Mike In Space
While sending a tribute from the 'invasion' to Emperor Bog, the Butt-Ugly Martians shrink the gifts so that they fit into the transporter. But they are unaware that they have shrunk Mike as well and accidentally send him to the Bog Star.

Whilst trying to rescue Mike, the Butt-Uglies become ensnared in a double-crossing scheme set up by Emperor Bog. Will Mike return to Planet Earth safely? Will the Butt-Uglies be found out by Emperor Bog? Will Stoat Muldoon discover the Butt-Uglies?

Bog In Charge
The kids get Muldoon to help rescue the Butt-Ugly Martians. Shocked at the alien invasion forces, Muldoon vows to fight to the end to help protect the planet.

The Butt-Uglies have a plan that should trick Bog into an attack that they think will result in the capture of the Martian Emperor, but also need to deal with Muldoon. Can they get rid of Bog for good and escape Muldoon?
