No worries! Although I should probably mention that these buses were originally built on a bendy bus chassis, but ComfortDelGro (the company that makes the final bus) heavily modified it so it's no longer a bendy bus (they call it a "beach tram" because it connects people to different beaches at Sentosa). Unlike a proper bendy bus you cannot walk through the bendy bit as that's where the two sections are connected, which is why I say it's a bus-like trailer.
