This one, titled 'UFO Spin', sees the pair deploy their new UFO move in an attempt to remove a runaway coin from a nearby drain. Once again, there's no actual gameplay to be seen here, but if you need convincing that the series' slapstick humour is present and correct, look no further.

Brothership adds more RPG depth to the series, but its flat writing and overabundance of gimmicks drag it down.

I used to play Mario & Luigi RPGs on the Nintendo DS a long time ago. I always got a kick out of how they cleverly blended controls for both Mario and Luigi with button-mapping, making it feel like you were taking both on an adventure.
