The first was about a mouse who's grown too fat... I apologise - we don't have English translations yet, so you'll just have to endure the gorgeous female German voice at the end. Heidi Klum, anyone? Ah, a man can dream. But for those of you who don't sprachen ze Deutsche, the basic thrust of the tagline is "House too small? Maybe it's time to move..."
The second advert was about a cuckoo who has a tough gig. I'm showing you the French version because the timing on the last joke is better. To those of you who don't parle vous Francais, the gorgeous female voice at the end is saying something along the lines of "Tired of your commute? Maybe it's time to move..."
The last one is about a Penguin who's thinking "There goes the neighborhood". The german at the end says something like "Neighbors got you down? Maybe it's time to move..." For all its simplicity, this one is my favorite, particularly the igloo gag at the end.
