If there was an ending band sequence...
...for Castle Crashers, this would totally be it.
Imagine...you've saved the land, and you throw a concert for the maidens/princesses.
Bam, the band from the beginning of the game bust through th walls and emerges with an Electric guitar! Let's all rock out!!! Whoo!
But let us be serious. It was awesome, plain, short, and simple.
(Well, the making of it probably wasn't simple, but I'm sure you understand.)
