Who knew baby penguins were so street? That’s what it appears is the in thing in Happy Feet two, where there are plenty more dancing penguins. Mumble is now grown up and has a baby of his own. However young Erik is reluctant to dance, as he’s not very good. As a result Erik runs away and encounters The Mighty Sven – a penguin who can fly! Mumble has no hope of competing with this charismatic new role model. But things get worse when the world is shaken by powerful forces. Erik learns of his father’s ‘guts and grit’ as Mumble brings together the penguin nations and all manner of fabulous creatures – from tiny Krill to giant Elephant Seals – to put things right. The movie is out in the UK on December 2nd, but now a new full trailer has arrived, which you can see below, as well as the poster above.
