Appeared in Ghostbusters-Father Knows Beast
Voiced by Erika Scheimer

Mac was a nine year old Scottish boy in 1986, who while visiting his friend Willy at Willy's family castle, was inspired by Willy's Uncle Dougall's ghost stories to find evidence hidden away in the castle.

When the two boys noticed a glowing brick in a wall, they found an old urn hidden behind it and Mac encouraged Willy to open it. This caused Slort, King of Trolls to escape his 40 years imprisonment. Mac immediately took off and left Willy alone to face the troll.

After Slort had been defeated by the combined might of the Junior and Senior Ghostbusters, Uncle Dougal made sure Willy and Mac learned their lesson by having them clean the castle.


Mac made his only appearance in the episode Father Knows Beast
