Captain Flinn and the Pirate Dinosaurs
Sings Of Silliness
S1 E37:
When his majesty the King puts up confusing 'road signs' all over the sea, it creates chaos. The pirate dinosaurs exploit the situation and put up their own signs to lead ships into a trap where they are to pillaged by the rotten reptiles who are lying in wait. It's only when the King himself falls victim to their tricks, and is saved by Captain Flinn.
