Double Trouble (1972) - The Amazing Chan and the Chan Clan Cartoon Episode Guide

Like Josie and the PUssycats, the Chan Clan must contend with how so much music comes from a guitar, a drum set and tambourines. At least the Chan Clan has the addition of a clarinet and trombone at other times.
The song this time is "Who Stole My Heart Away" while better than "Undercover Man" and Super Sleuth" it still isn't a winner.
It is also amazing that the cartoon had to recast voices due to accents being too thick, as with ten children characters, they are all distinctly identifiable if heard speaking.
Entertaining comedy exchange between Flip and Stanley.
"What's aft?" Stanley asks.
"Opposite of fore."
"What's fore?"
"Forget it!"
The smallest group gets a bit more play here, being Flip, Nancy, Mimi and Scooter.
Chu Chu mimicks a siren here as he did in other shows as well.
The mystery of the missing prince is low key to the kids antics and rather vague as to why there are monsters on the ship.
