All's Fare in Love and Taxis - S3.E10

The gang tries to cross the marshlands but have problems with getting a cheap taxi. In the end they took Sandra's offer of 700 gold. The first half of the journey was a roller coaster ride with Golem barely hanging on! Halfway through the marshlands, Sandra suddenly stops and tells them that she is going back!

It turns out that she is trying to rip them off since she knows they are loaded for their victory in the last competition is all over the news. She asks for 3000 more gold and they broke out into an argument. After failing to reach an agreement, Sandra threatens to leave them in the marshland. The gang decided to perform to get a price cut and in the end managed to resolve it for another 1000 gold against the backdrop of going deaf from Mocchi's singing.
