Monster Beach - Season 1 - Eps 15: Treasure Hunters
Widget and Brainfreeze find a treasure map (it was in Brainfreeze's pocket but he's just as surprised as everybody else is). They set off to find the buried treasure, keenly assisted by Jan and Dean. Soon they're joined by, well, pretty much every monster on Monster Beach. The only trouble is, nobody is very good at reading maps... and what is this treasure anyway?
