In this animated cartoon, Blue is happy-go-lucky, while Red can't seem to get a moment of peace from Blue's consistently adorable chattering.
Life is tough for a cube. Red is just trying to make it in what he believes is a harsh world. Things don't ever really go well for him, especially when Blue is around, which he always is. Blue is just a happy-go-lucky cube who sees the joy in everything around him, even Red. So, of course, Blue irritates Red and hilarity ensues.
