The town is also suffering from a mysterious illness found in the children, apparently due to pollutants being pumped into the sea by a local factory.

The local children befriend Ollie, who informs them that the pollution in Earth's atmosphere is causing things created by his species – like the probe – to malfunction.

He possesses a mysterious ball which can be used to fix broken and/or damaged objects and cure the illness being caused by the pollutants (although he claims that this feature cannot be used too often).

To cover for Ollie's increasing hunger and clumsiness, she pretends that she can do magic to account for some of the objects he has knocked over while invisible, which gets the attention of the press.

He is arrested and fined at the end of the series after the authorities find out about his illegal activities, although he redeems himself by helping Ollie reach the probe before it explodes at the last minute.
